The market showed signs of strength yesterday, but we’ll keep taking it one day at a time. The biggest story in markets yesterday was Jerome Powell and the Fed:Fed Chairman Jerome Powell: 1. "We will use our tools to get inflation back" 2. "If we have to raise rates more, we will" 3. "We probably remain in an era of very low interest rates" 4. 'It's a long road to normal' monetary policy All these statements contradict each other. Which is the point. Rate hikes have priced in to markets over the last month or so… So let’s move on to where we can make some money!EM is the best opportunity of 2022It looks to us like the tech market is nearing a short term low.Via Bloomberg/Sundial Research. 40% of stocks on the Nasdaq are down 50%+ from their 52 week high. More interesting in the context of the Nasdaq still near ATHs, which hasn’t happened before.The only other time this many stocks were down so much with the Nasdaq near a high was late 1999. The generals do generally get shot last. The generals are much cheaper, are arguably under-earning, have higher ROICs and are growing faster vs. 1999/2000 - many of them are basically just levered royalties on global GDP. SAAS: The superb QDS team at MS showing that their Crowded Longs (CRWD) and Expensive Tech (EVSA) baskets are 85% of the way through their typical downside move during a "rate shock" vs. indices only 40-50% of the way through. Software now approaching 2019 trough valuations.Combined with extremely light positioning in tech/growth by funds (nearing 5-10 year lows), the set up looks increasingly attractive.The issue growth stocks have is they are too expensive relative to the underlying growth, so there is no buyer. The only analysis that matters is how much do they need to grow over what time or how low do they need to go before they are attractive.RM Thesis: Growth is not broken. Far from it. This is a very healthy reset in QLCF (quality lacking cash flow™️) that will only last as long as big scary inflation headline #s do. When the scary headlines go away, multiples will expand and capital will flow back to the companies that define our future rather than the paint our past. Any 10 year rate below 4% is not going to suck a lot of $capital away from equity so money from everyone is still going to be looking for a home in the market. I don’t think we see multiples snap back - that party is over for now. However, I’m not paradigm shift where ‘value’ is king for years. Pain should end for best in class SMIDs before yr end but The cohort of “best in class” is always at best 20% of what people think actually belongs💸Reformed Millennials - Post of The Week21 Ideas from 2021 from David Parrel.Our favorites are highlighted.1. The Mind Creates Reality: The American Psychological Association once invited William James to give a talk on the first 50 years of psychology research.He simply said: “People by and large become what they think of themselves.”Then, he left.2. Make One Person Responsible: If you want to get something done, it’s tempting to put a huge number of people in charge. But often, when too many people are in charge, nobody accepts responsibility.This saying is illustrative: “A dog with two owners dies of hunger.”3. Kanye West, on Genius: "If you guys want these crazy ideas, these crazy stages, this crazy music, this crazy way of thinking, there’s a chance it might come from a crazy person.”4. The Knife Theory of Hiring: When you first start a company, you need Swiss Army Knife people who can do a little bit of everything. Once your company gets big, you need a bunch of kitchen knife people who do one thing very, very well.5. Sayre’s Law: In a dispute, the level of emotions are inversely related to what’s at stake. That’s why unimportant events can inspire such passionate arguments. In parts of academia, they say: “The battles are so fierce because the problems are so trivial.”6. Braess’ Paradox: Adding capacity to a system can counterintuitively slow things down. Highways are the classic example. For years, road designers have observed that adding more roads to a network can actually increase congestion and slow the flow of traffic.7. Current vs. The Wind: Novice sailors focus on the wind. Experienced ones study the currents. Since the winds change every day, the knowledge is ephemeral. But currents are persistent and predictable, even if they’re hard to see. Focus on the currents in life.8. Akrasia: In theory, we know how to behave. But in practice, we don’t always do it. The Ancient Greeks called this phenomenon “akrasia,” which translates to “weakness of will.” It describes our tragic proclivity to act against our best interests, even when we know what to do.9. Paradox of Consensus: Under ancient Jewish law, if a suspect was unanimously found guilty, they were deemed innocent. Total agreement signaled a systematic flaw in the judicial process. Often, when everybody is thinking alike, nobody is thinking at all.10. The Paradox of Weirdness: The weird parts of ourselves are actually the thing that’s normal. People are actually weird. It’s how we’re born. What’s weird is the way social conditioning makes us seem more similar than we really are. - Tyler Cowan11. Make Uphill Decisions: If you’re split between two decisions and don’t know which one to choose, default to the one that’s more difficult in the short-term. - Naval Ravikant12. Nullius in Verba: This is Royal Society’s old motto. It translates to “take no one’s word for it.” Be curious. Figure things out for yourself. Move through the world with a posture of productive skepticism and when it comes to truth, do your own investigations.13. Otium: The Latin word for leisure. But not the lazy kind of leisure where you sit around and do nothing. It’s the Ancient Roman kind where you play sports, contemplate life, and consume great art. This is how I aspire to spend my weekends.14. Luxury Beliefs: People have always signaled status by buying expensive things. But now they do it by holding certain beliefs, which confer status on upper class people while inflicting costs on lower class ones. - Rob Henderson15. Pre-Headline vs. Post-Headline People: Pre-headline people know about things before they make it into the news. Post-headline people only know about things after they’re printed and become well-known. Pre-headline people have the edge in life. - Balaji16. Robustness Principle: A design guideline for software developers that applies to many things in life: “Be conservative in what you do, but liberal in what you accept from others.”17. Serving vs. Served: Self-sacrificial service is the great paradox of life. The more you give, with no expectation of reciprocity, the happier you will be. In a world of utility-maximizing selfishness, this is counterintuitive and counter cultural. - Brent Beshore18. Yuck and Yawn: If you want to start a profitable business, look for opportunities that are smelly (like trash collection) or ones that are boring (like niche materials). Avoid sexy industries like the ones prestige-thirsty MBA students tend to pursue. - AUM Energy19. The Story of Damocles: A man once got to be king for a day and sit on the king’s luxurious throne. From afar, the throne looked peaceful. But to his surprise, a sword hung above it. Immediately, Damocles learned that with great power comes great fear, anxiety, and danger.20. Planck’s Principle: Scientific knowledge doesn’t change because scientists change their mind. Rather, it changes as old scientists die, new ones are born, and a new generation of scientists gains influence.21. The Stupid Test: Peter Thiel once said: “As an investor, you want to find things that are so stupid that people are embarrassed to invest in them.“ Often, the best opportunities are the simplest. Unfortunately, people miss them because they think good ideas must be complex.Last Quarter App Downloads for Meta: $FB“Instagram had its BEST quarter for downloads since at least 2014, and Q4 2021 was the FIRST time Meta had the top app since Q4 2019.”Inspirational Thread:🌊 Canadian Companies To Peruse 🌊Headversity - Calgary based company raises $12.5m CAD Series A - Headversity is a workplace mental health and resilience platform helping workers through mental health issues. 🔮Best Links of The Week🔮Is $13b for Opensea crazy?

Y., Jung, S., Bi, G., Tsien, R. W., Park, H. Abstract: The balance between excitation and inhibition is essential for maintaining proper brain function in the central nervous system. Inhibitory synaptic transmission plays an important role in maintaining this balance. Inhibitory synaptic transmission faces greater kinetic demands than excitatory synaptic transmission, yet remains less well understood. In particular, the dynamics and exocytosis of single inhibitory vesicles have not been investigated due to both technical and practical limitations. Using quantum dots (QDs)-conjugated antibodies against the luminal domain of the vesicular GABA transporter (VGAT) to selectively label single GABAergic inhibitory vesicles and dual-focus imaging optics, we tracked single inhibitory vesicles up to the moment of exocytosis (i.e., fusion) in three dimensions in real time. Using three-dimensional trajectories, we found that the total travel length before fusion of inhibitory synaptic vesicles was smaller than that of synaptotagmin-1 (Syt1)-labeled vesicles. Fusion times of inhibitory vesicles were shorter compared with those of Syt1-labeled vesicles. We also found a close relationship between release probability to the proximity to fusion sites and total travel length of inhibitory synaptic vesicles. Furthermore, inhibitory synaptic vesicles exhibited a higher prevalence of kiss-and-run fusion than Syt1-labeled vesicles. Thus, our results showed that inhibitory synaptic vesicles have the unique dynamics and fusion properties that facilitate their ability to support fast synaptic inhibition.

Sophia Chen of MRS Bulletin interviews Dan Walkup of the National Institute of Standards and Technlogy about an unusual concentric quantum dot structure created in graphene. Read the abstract in Physical Review B .TranscriptSOPHIA CHEN: Physicist Dan Walkup has a mystery on his hands. Working at the National Institute of Standards and Technology in Gaithersburg, Maryland, his team has engineered a strange phenomenon in the 2D material graphene using a scanning tunneling microscope, or STM. They created the phenomenon by accident playing around with the STM, whose very sharp tip manipulates single atoms on a material. In the graphene it created a quantum dot (QD). DAN WALKUP: Historically we weren’t trying to study coupled QDs per se. We were trying to figure out how to tune the properties of the graphene with STM tip. In that way we came eventually to this QD study. SC: You can visualize the QD as an island in the graphene, where electric charges are confined and isolated from the rest of the material. At the QD, negative electrons gather around positive electron holes. They can also do the charge inverse of this, where the positive holes go around a negatively charged nucleus. From this, you might get the sense why QDs are sometimes known as artificial atoms. Like atoms, quantum dots consist of one type of charge going around a nucleus of the opposite charge. The researchers have taken the graphene, stuck it on a substrate of hexagonal boron nitride, and manipulated the electric charges with the STM inside these two materials to create the QD. DW: We create a little pocket of charge in the hexagonal boron nitride, and that charge pocket attracts oppositely charged electrons in the graphene and makes a little charge pocket in the graphene, which becomes a QD. SC: But this isn’t your garden variety QD. The geometry of this particular island has never been seen in graphene. By using the STM and applying a strong magnetic field to the material, Walkup’s team has made a nested QD, one island of charge stacked on the other. From overhead it looks like a bulls’ eye, with one island of charge at the center, and another forming a ring around it. DW: The two dots are like the two tiers of this wedding cake.SC: They’re two concentric quantum dots: one dot is in the center and the other dot is the ring around the first. These two structures are distinct quantum dots because electrons from one island are generally confined to that island. Walkup’s team ran some experiments in which they added electrons to each quantum dot. They did this by applying a voltage to the back of the material, causing electrons to move toward each dot. The researchers can then monitor where the electrons go using the scanning tunneling microscope. And what they found was puzzling. They found that as they added electrons to either of the two quantum dots, they behaved in a way that can’t be explained by accepted models of quantum dot physics. Walkup says you would expect the two dots to repel each other as you add electrons to them, since negative charges repel each other. But the inner dot only cared about its own charge. It did not care about the charge of the outer dot. Whereas the outer dot responded to the combined charge of both dots. They want to figure out why. DW: Part of this paper is an open invitation to the theorists in the world to figure out why it is this way instead of some other way. SC: A better understanding of the basic physics of this bizarre quantum dot configuration could help the development of applications such as quantum computing, in which information is stored in the way quantum dots share electrons. This work was published in a recent issue of Physical Review B.

Infinitesimally small quantum dots can turn a window into a see-through solar panel! Thanks to the University of Minnesota for sponsoring this video! http://twin-cities.umn.edu/ Thanks also to our supporters on https://www.patreon.com/MinuteEarth ___________________________________________ If you want to learn more about this topic, start your googling with these keywords: Solar window: a window that functions like an ordinary window but also generates power like a solar panel Nanoparticle (also called nanopowder or nanocluster or nanocrystal): a microscopic particle with at least one dimension less than 100 nm. These tiny objects often have characteristics that differ from larger versions of the same material. Quantum dots (QD): tiny nanoparticles of some kind of semiconducting material, only several nanometers in size, so small that their optical and electronic properties differ from those of larger particles. The QDs embedded in solar windows can absorb radiation largely in short wavelengths and re-emit in longer wavelengths; useful for capturing solar energy and successfully tranferring it to the solar cells on the edges of the pane. ___________________________________________ Credits (and Twitter handles): Script Writer: Peter/Emily Script Editor: Alex Reich (@alexhreich) Video Illustrator: Qingyang Chen (@QCVisual) Video Director: Kate Yoshida (@KateYoshida) Video Narrator: Kate Yoshida (@KateYoshida) With Contributions From: Henry Reich, Ever Salazar, Emily Elert, Peter Reich, David Goldenberg Music by: Nathaniel Schroeder: http://www.soundcloud.com/drschroeder Image Credits: Thumbnail: R.

Does it seem counterintuitive to you that by leaving money on the proverbial sales table you could actually increase your bottom line? While it may seem that way at first glance, today's guest shares how that is what has been happening in his business. On this episode of Grow My Revenue I'm joined by Sean Farrell of Quality Data Systems (QDS), and he explains how they've used integrity-based sales to exponentially grow their company. For a few years now QDS has focused more on their clients and the solutions those clients need, that has tripled QDS' bottom line. Listen in for real-life examples and how using an integrity-based approach to selling has created so much growth for QDS, and can for you too. Listen to this episode and discover: - Why doing the right thing now can lead to bigger deals in the future. - What is integrative sales really about? - How focusing on results generates better outcomes for them and their clients. - Will more questions equal a longer sales cycle? - How QDS tripled their bottom line without pursuing triple the amount of opportunities. - And so much more… Episode Overview Sean Farrell has been the CEO of Quality Data Systems for a few years now even though he never intended to go into the family business. QDS was a company his dad started in 1983, but it was his dad's work and not of interest to Sean. Sean had other ideas: he played collegiate baseball at the University North Carolina and was later drafted by the Oakland Athletics. When he tore up his shoulder diving for a ball in the outfield Sean went through several surgeries, none ever fixing it properly. Between the injury and the incredibly low pay of the minor leagues he opted to make some cash by going into sales. Soon he found his competitive nature taking over and discovered his love of sales. Landing a deal was just as sweet to him as hitting a home run! Thirteen years later he is still at QDS and loving the work he does there. When Sean's dad started the company and still today QDS sells and services money-handling equipment for banks, credit unions, and retail. Anyone who handles cash, coin or check can be served by a product or offering QDS has available. Over the years that has evolved from desktop products to integrative systems and solutions, that integration at Sean's behest. On this episode of Grow My Revenue, Sean and I take a snapshot look at what QDS was doing prior to the implementation of integrity-based sales, and what they've been doing since implementing this new way of doing business. Plus Sean gives a real-life example of integrity based sales and how he served his clients' needs with a much smaller monetary investment (even when he knew the client had a sizable budget for the solution). Sean explains that by focusing on how QDS solved similar problems for previous clients the company presents itself in a way that opens doors with potential new clients. QDS' approach now is simply they are there to solve the problems clients have and deliver the results the clients need. Price is rarely a key driver in those conversations today because it's all about the value and results QDS provides, and as a result it's actually helped QDS become more profitable. Another surprising share on this episode is Sean's real-life example of providing a very inexpensive solution to a client with a large budget - and how that won QDS a role as a trusted advisor to the client and led to more sales in the future. This is an episode you don't want to miss, especially if you've been considering implementing an integrity-based sales approach for your team. There's all of that and so much more on today's episode of Grow My Revenue! Discover more at http://www.ianaltman.com/business-cast/

Electron spins confined in quantum dots (QDs) are among the leading contenders for implementing quantum information processing. In this Thesis we address two of the most significant technological challenges towards developing a scalable quantum information processor based on spins in quantum dots: (i) decoherence of the electronic spin qubit due to the surrounding nuclear spin bath, and (ii) long-range spin-spin coupling between remote qubits. To this end, we develop novel strategies that turn the unavoidable coupling to the solid-state environment (in particular, nuclear spins and phonons) into a valuable asset rather than a liability. In the first part of this Thesis, we investigate electron transport through single and double QDs, with the aim of harnessing the (dissipative) coupling to the electronic degrees of freedom for the creation of coherence in both the transient and steady-state behaviour of the ambient nuclear spins. First, we theoretically show that intriguing features of coherent many-body physics can be observed in electron transport through a single QD. To this end, we first develop a master-equation-based formalism for electron transport in the Coulomb-blockade regime assisted by hyperfine (HF) interaction with the nuclear spin ensemble in the QD. This general tool is then used to study the leakage current through a single QD in a transport setting. When starting from an initially uncorrelated, highly polarized state, the nuclear system experiences a strong correlation buildup, due to the collective nature of the coupling to the central electron spin. We demonstrate that this results in a sudden intensity burst in the electronic tunneling current emitted from the QD system, which exceeds the maximal current of a corresponding classical system by several orders of magnitude. This gives rise to the new paradigm of electronic superradiance. Second, building upon the insight that the nuclear spin dynamics are governed by collective interactions giving rise to coherent effects such as superradiance, we propose a scheme for the deterministic generation of steady-state entanglement between the two nuclear spin ensembles in an electrically defined double quantum dot. Because of quantum interference in the collective coupling to the electronic degrees of freedom, the nuclear system is actively driven into a two-mode squeezedlike target state. The entanglement buildup is accompanied by a self-polarization of the nuclear spins towards large Overhauser field gradients. Moreover, the feedback between the electronic and nuclear dynamics is shown to lead to intriguing effects such as multistability and criticality in the steady-state solutions. In the second part of this Thesis, our focus turns towards the realization of long-range spin-spin coupling between remote qubits. We propose a universal, on-chip quantum transducer based on surface acoustic waves in piezo-active materials. Because of the intrinsic piezoelectric (and/or magnetostrictive) properties of the material, our approach provides a universal platform capable of coherently linking a broad array of qubits, including quantum dots, trapped ions, nitrogen-vacancy centers or superconducting qubits. The quantized modes of surface acoustic waves lie in the gigahertz range, can be strongly confined close to the surface in phononic cavities and guided in acoustic waveguides. We show that this type of surface acoustic excitations can be utilized efficiently as a quantum bus, serving as an on-chip, mechanical cavity-QED equivalent of microwave photons and enabling long-range coupling of a wide range of qubits. In summary, this thesis provides contributions towards developing a scalable quantum information processor based on spins in quantum dots in two different aspects. The first part is dedicated to a deeper understanding of the nuclear spin dynamics in quantum dots. In the second part we put forward a novel sound-based strategy to realize long-range spin-spin coupling between remote qubits. This completes a broad picture of spin-based quantum information processing which integrates different perspectives, ranging from the single-qubit level to a broader quantum network level.

Methods based on nanotechnologies play a growing role in biomedical research. Quantum dots (QDs) are a group of engineered fluorescent nanoparticles suited for advanced imaging applications. The substitution of the particle’s surface with defined molecular structures could enable the adoption as targeted contrast agents or therapeutic devices for a variety of clinical approaches. However, important aspects such as the basic surfacedependent behavior of non-targeted QDs in the organism and arising health effects upon systemic administration remain incompletely understood. Acute inflammatory effects for instance are often initiated on the microcirculatory level and are probably relevant for cardiovascular pathologies observed in epidemiologic and experimental studies of certain nanoparticles. Most in vitro studies show that the surface structures of QDs and other nanoparticles seem to be predominantly accountable for different cytotoxic effects and a variable potential to liberate proinflammatory cytokines. Currently, no systematic in vivo studies have addressed surface-dependent interactions of QDs on the level of the microcirculation and assessed the resulting impact on biokinetics as well as on proinflammatory parameters. Thus, this thesis aimed to i) analyze the incidence of QDsurface- dependent acute microvascular interactions and their influence on key biokinetic parameters and ii) investigate acute immunomodulatory effects on the multistep process of leukocyte recruitment in vivo. For this, three types of commercially available QDs with different surface modifications: carboxyl-QDs, amine- and polyethylene glycol-QDs (amine-QDs) and polyethylene glycol-QDs (PEG-QDs) were used. The physicochemical characterization was done by dynamic light scattering (DLS) analysis and microscale thermophoresis. In a first set of experiments, circulating half-lives, tissue distribution in different organs, and hepatic as well as renal clearance were measured. Ex vivo analysis of QD tissue distribution was performed on selected tissue samples via transmission electron microscopy (TEM) and two-photon microscopy. By combining reflected-light oblique transillumination (RLOT) and fluorescence in vivo microscopy of the murine M. cremaster, interactions of QDs with components of the microcirculation as well as leukocyte migration parameters were visualized and quantified. The extreme short circulating half-life of anionic carboxyl-QDs was related to pronounced clearance by the mononuclear phagocyte system. Beyond this, further investigations showed, for the first time, that the continuous capillary endothelium of skeletal and heart muscle tissue has the capacity to directly extract carboxyl-QDs from the circulation by means of caveolaemediated endocytosis. Carboxyl-QDs were also taken up by perivascular macrophages in the surgically exposed but not in the native M. cremaster and led to a significant increase of adherent and (subsequently) transmigrated leukocytes in this model. Further experiments provided evidence for a probable involvement of mast cells in the intercellular adhesion molecule-1 (ICAM-1)- and endothelial (E)-selectinmediated modulation of leukocyte recruitment. This process is most likely initiated by the endocytosis of carboxyl-QDs through activated perivascular macrophages. The primary activation of tissue-resident perivascular macrophages seems to be the consequence of tissue damage related to the surgical preparation of the cremaster muscle. This is supposedly a prerequisite for the endocytosis of carboxyl-QDs whereupon endothelial and mast cells seem to be secondarily activated in a paracrine fashion that then leads to an increase in leukocyte recruitment.

The use of PbS quantum dots (QDs) acting as light absorbers in a range of nanostructured solar cell devices has been investigated. The impact of different QD deposition methods, of the nature and structure of different metal oxides serving as electrodes, as well as interface and surface effects on device performance has been explored. Chapter 3 describes the application of in situ grown PbS QDs as absorber layer for extremely thin absorber solar cells with the inorganic solid hole transporter CuSCN. A polystyrene-block-poly(ethylene oxide) block copolymer was employed as a structure-directing agent for the synthesis of mesoporous TiO2 metal oxide thin films with high surface area and ordered porous structure. Chapter 4 outlines further work in which water-solubilized ex situ grown QDs capped with L-glutathione ligands were employed in order to improve the loading of the PbS QDs onto the internal surface of the porous oxide. Successful sensitization was achieved by inducing opposite surface charges on the surfaces of the QDs and the oxide in order to attract and attach QDs onto the surface of the porous supporting oxide film. The sensitized TiO2 electrodes were used to make efficient liquid electrolyte quantum-dot-sensitized solar cells (QDSCs). Chapter 5 describes the use of SnO2, which has a lower lying conduction band than TiO2, to fabricate scaffolding electrodes that were sensitized with water-solubilized PbS QDs. Passivation of the SnO2 electrodes with a thin layer of MgO, TiO2 and a combination of both was utilized to investigate the effect of surface treatments on the performance of solid-state QDSCs, using Spiro-OMeTAD as organic hole transporter. Chapters 6 and 7 deal with different approaches towards interface tuning in solid-state QDSCs. This part of the work involved the study of solar cell devices utilizing in situ grown PbS QDs with and without organic and inorganic surface passivation, and ex situ grown PbS QDs anchored on mesoporous TiO2 via organic linker molecules. The performance of the fabricated solar cells was evaluated with standard current-voltage and incident-photon-to-collected-electron efficiency measurements, and physical parameters of the devices were characterised with frequency- and time-resolved techniques such as electrochemical impedance spectroscopy, intensity-modulated photovoltage/photocurrent spectroscopy, and open circuit voltage decay measurements, respectively. Overall, the work highlights the importance of surface passivation of QDs, loading of the QDs onto porous semiconducting oxide electrodes, as well as the significance of interfacial effects between QDs, oxides and hole transporter to achieve high-efficiency devices.

This thesis contributes to the understanding of impurity models. It is divided into two main parts, with a general introduction given in Part I and the research related to it presented in Part II, with the second part being subdivided into two main projects. In the first project, the influence of two many-body effects, the Kondo effect and the Fermi edge singularity, on the absorption and emission spectra of self-assembled quantum dots (QDs) is examined. Whereas the Kondo effect so far was always examined with transport experiments, we show that it has been observed with optical methods for the first time, by comparing experimental data for the absorption line shapes of QDs to calculations with the numerical renormalization group. We continue by examining a QD with strong optical coupling of the energy levels. The resulting interplay of Rabi-oscillations and Kondo effect leads to a new many-body state, a secondary, outer Kondo effect, with Kondo-like correlations between the spin-Kondo and the trion state. The last work regarding optics at QDs addresses the Fermi edge singularity. We show that for QDs this phenomenon can be described numerically on a quantitative level. The second project concerns transport properties of impurity models. First, we present a comprehensive study of the Kondo effect for an InAs-nanowire QD, a system for which the Kondo effect was observed only a few years ago. The second study regarding transport concerns the Kondo effect in bulk metals with magnetic impurities. Although nowadays the Kondo effect is often studied with QDs, it was discovered for iron impurities in noble metals like gold and silver. However, it was unknown for a long time which exact realization of Kondo model describes these systems. We identify the model by comparing numerical calculations for the magnetoresistivity and the dephasing rate for different models to experimental results. The third work about transport concerns the phenomenon that for a fixed type of Kondo model quantities like the magnetoresistivity or the conductivity, respectively, can be scaled onto a universal curve for different parameters, when energies are rescaled with the the Kondo temperature $T_K$, since it is the only relevant low energy scale of the problem. For finite bandwidth, however, different definitions of $T_K$ (which coincide in the limit of infinite bandwidth) lead to different $T_K$-values. We show that with a very common definition of $T_K$, finite bandwidth, which is always present at numerical calculations, can deteriorate the universality of rescaled curves, and we offer an alternative definition of $T_K$ which ensures proper scaling. In the last study presented in this thesis we calculate the Fermi-liquid coefficients for fully screened multi-channel Kondo models. For temperatures below $T_K$, these models show Fermi-liquid behavior, and the impurity density of states and certain quantities which depend on it, like resistivity, show quadratic dependencies on parameters like temperature or magnetic field, described by the Fermi-liquid coefficients. We calculate these coefficients both analytically and numerically.

This work focuses on the investigation of overgrowth phenomena in InAs/GaAs nanostructures using synchrotron radiation. Surface-sensitive grazing incidence small angle x-ray scattering (GISAXS) and grazing incidence diffraction (GID) are applied to study shape, strain, and interdiffusion in self-organised grown nanostructures. The technique of anomalous x-ray diffraction at the weak (200) superstructure reflection enhances the chemical sensitivity of the measurements. For the investigation of (partially) buried nanostructures finite-element simulations (FEM) have been performed. The following sample systems were investigated: ((1)) Free-standing and buried InGaAs quantum dots: Free-standing In(x)Ga(1-x)As islands grown on GaAs (001) by molecular beam epitaxy (MBE) with a nominal concentration of x=0.5 have been investigated. Contrast variation close to the K edge of As by anomalous GID at the (200) superstructure reflection is used for a direct determination of the InAs concentration as a function of the lateral strain in the quantum dots (QDs). The evaluation of intensity mappings recorded in reciprocal space close to the (200) reflection together with atomic force micrographs (AFM) allows to attribute the strain and the InAs concentration to a certain height in the quantum dots. Thereby, a three-dimensional model of the strain and interdiffusion profile of the InGaAs QDs can be reconstructed. A discussion of measurements taken on buried InGaAs QDs and free-standing islands grown on the strain modulated surface of a buried QD layer shows the limits of this technique. ((2)) InGaAs quantum rings: The formation of nanoscopic InGaAs ring structures on a GaAs (001) substrate takes place when InAs quantum dots, grown by Stranski-Krastanov self-organisation, are covered by a thin layer of GaAs. The shape transformation into rings is governed by strain, diffusion and surface tension, quantities which are of importance to understand magneto-optical and electronic applications of the rings. GISAXS and GID is applied to characterise morphology and structural properties such as strain and chemical composition of the rings in three dimensions. From GISAXS the shape is found to be of circular symmetry with an outer radius of 26nm, a height of 1.5nm, and a hole in the middle, in good agreement with AFM measurements. The most surprising results are obtained from intensity mappings in reciprocal space close to the (220) and (2-20) reflection done in surface sensitive GID geometry. From a comparison of the intensity maps with FEM model calculations the InGaAs interdiffusion profile in the ring is determined. It strongly depends on the crystallographic orientation. In the ring a maximum InAs concentration of more than 80% along [1-10] is found while along [110] it is below 20%. This is explained by the preferred diffusion of In along [1-10]. ((3)) Quantum wires formed by cleaved edge overgrowth: Quantum wires (QWRs) fabricated by the cleaved edge overgrowth (CEO) technique use tensile strain to confine the charge carriers to one dimension. The cleaved edge of a pseudomorphically strained In0.1Al0.9As/Al0.33Ga0.67As superlattice (SL) is overgrown by a GaAs layer of 10nm thickness. The lateral charge carrier localisation in the overgrown layer is induced by the periodic strain modulation of the SL. Using GID this strain state of the system is determined. The strain modulation due to the overgrown superlattice occurs only within 3micron of the total wafer thickness of 150micron. The GID technique allows for a clear separation of the strain modulation in the cap layer and the superlattice underneath. It can be proved that the strain modulation in the GaAs cap layer is not of compositional origin but purely elastic with an average lattice parameter change of (0.8+-0.1)% with respect to relaxed GaAs. The strain profile obtained is confirmed by FEM model calculations.
