Available in PDF, EPUB and Kindle. Book excerpt: Advances in semiconductor technology have made possible the fabrication of structures whose dimensions are much smaller than the mean free path of an electron. This book gives a thorough account of the theory of electronic transport in such mesoscopic systems. After an initial chapter covering fundamental concepts, the transmission function formalism is presented, and used to describe three key topics in mesoscopic physics: the quantum Hall effect; localisation; and double-barrier tunnelling. Other sections include a discussion of optical analogies to mesoscopic phenomena, and the book concludes with a description of the non-equilibrium Green's function formalism and its relation to the transmission formalism. Complete with problems and solutions, the book will be of great interest to graduate students of mesoscopic physics and nanoelectronic device engineering, as well as to established researchers in these fields.

Available in PDF, EPUB and Kindle. Book excerpt: Ongoing developments in nanofabrication technology and the availability of novel materials have led to the emergence and evolution of new topics for mesoscopic research, including scanning-tunnelling microscopic studies of few-atom metallic clusters, discrete energy level spectroscopy, the prediction of Kondo-type physics in the transport properties of quantum dots, time dependent effects, and the properties of interacting systems, e.g. of Luttinger liquids. The overall understanding of each of these areas is still incomplete; nevertheless, with the foundations laid by studies in the more traditional systems there is no doubt that these new areas will advance mesoscopic electron transport to a new phenomenological level, both experimentally and theoretically. Mesoscopic Electron Transport highlights selected areas in the field, provides a comprehensive review of such systems, and also serves as an introduction to the new and developing areas of mesoscopic electron transport.

Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor technology has developed considerably during the past several decades. The exponential growth in microelectronic processing power has been achieved by a constant scaling down of integrated cir,cuits. Smaller fea ture sizes result in increased functional density, faster speed, and lower costs. One key ingredient of the LSI technology is the development of the lithog raphy and microfabrication. The current minimum feature size is already as small as 0.2 /tm, beyond the limit imposed by the wavelength of visible light and rapidly approaching fundamental limits. The next generation of devices is highly likely to show unexpected properties due to quantum effects and fluctuations. The device which plays an important role in LSIs is MOSFETs (metal oxide-semiconductor field-effect transistors). In MOSFETs an inversion layer is formed at the interface of silicon and its insulating oxide. The inversion layer provides a unique two-dimensional (2D) system in which the electron concentration is controlled almost freely over a very wide range. Physics of such 2D systems was born in the mid-1960s together with the development of MOSFETs. The integer quantum Hall effect was first discovered in this system.

This book was released on 2013-03-08 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the Fourteenth Thniguchi Symposium on the Theory of Condensed Matter, which was held from November 10 to 14, 1991, at the Shima Kanko Hotel, Shima, Japan. The topic of the symposium was Physics 0/ Mesoscopic Systems. Mesoscopic systems have been developed band in band with the recent progress in nanotechnology and are the melting pot of basic science and technology. In nanostructures, the quantum effect of the electron wave manifests itself because of the limited dimensionality of the structure. The most typical features of these structures are the discreteness of the energy spectrum and the interference effect of electron waves, which have led to various fascinating phenomena. The purpose of this symposium was to discuss the latest developments in mesoscopic systems, especially transport phenomena, from the viewpoint of basic physics. This volume starts with an introduction to the field of mesoscopic systems together with the paper by Prof. R. Kubo, who was the first to note the existence of particular features of discrete energy levels in small metallic particles. In Part II the electronic states of quantum dots and the conductance through them are discussed. Tunneling via small structures and junctions is studied in Part ill.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a snapshot of the vision shared by outstanding scientists on the key theoretical and experimental issues in Mesoscopic Physics. Quantum properties of electrons in solid state devices and transport in semiconducting and superconducting low-dimensional systems, are discussed, as well as the basis of quantum computing (entanglement, noise decoherence and read-out). Each chapter collects the material presented at a Varenna School course of last year, by leading experts in the field. The reader gets a flavor, how theorists and experimentalists are paving the way to the physical realization of solid state qubits, the basic units of the new logic and memory elements for quantum processing. He will be surprised in finding that mesoscopic solid state devices, which were invented just yesterday ( think of the Single Electron Transistor, or the Cooper Pair Box) are currently used as charge-sensing applications in the equipment of frontier research laboratories. These devices contribute as probing systems to produce evidence on still unsettled questions in topics like the metal-insulator transition in disordered two dimensional systems, quantum Hall conductance in heterostructures, or Kondo conductance in quantum dots.

Available in PDF, EPUB and Kindle. Book excerpt: "The aim of this thesis is to extend the theoretical framework of nonequilibrium electronic transport to incorporate quantum effects in disordered mesoscopic systems. Our theoretical methods are developed based on the diagrammatic perturbation technique formulated with the Keldysh nonequilibrium Green's functions. Given the real-space Hamiltonian of the transport system together with thermal reservoir parameters, we seek to compute the electronic structure and the charge current taking the various quantum effects into account. Following this methodology, the three most important and ubiquitous disordered mesoscopic effects are addressed, viz. weak localization, energy relaxation, and the Altshuler-Aronov (AA) effect, all of which give rise to corrections to the classical Drude description of electronic transport. Specialized theoretical methods are developed for the respective physical effects. For weak localization we develop a Cooperon-based diagrammatic scheme using the so-called dual fermion (DF) technique in order to take into account nonlocal interference processes which have been neglected in the prevailing coherent potential approximation (CPA). Numerical simulations have shown that, compared to CPA, our DF method yields more accurate results for transport properties of disordered quantum wires, and that in particular it is able to predict the negative magnetoresistance effect which is a signature of weak localization. The energy relaxation in disordered interacting wires is tackled with a self-consistent GW-CPA scheme. Using this computational method we study how the energy distribution of interacting electrons evolves under increasing interaction and external field strengths. In addition, the same computational scheme is also employed to simulate the Coulomb drag effect between parallel quantum wires. The interesting dependence of nonequilibrium drag current on the chemical potentials of reservoirs is discussed. As to the AA effect, the original diagrammatic formulation by Altshuler and Aronov is generalized to the real-space Keldysh formalism. Then, both theoretical and numerical diagram calculations show that for a disordered wire at nonequilibrium the AA effect leads to anomalous DOS corrections at its respective Fermi energies, and that the magnitudes of these (local) DOS corrections are position-dependent. The AA effect on transport properties is also analyzed, which shows nontrivial behaviors with respect to system sizes and bias voltages"--

This book was released on 2012-12-06 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: The articles in this book have been selected from the lectures of a NATO Advanced Study Institute held at Bad Lauterberg (Germany) in August 1995. Internationally well-known researchers in the field of mesoscopic quantum physics provide insight into the fundamental physics underlying the mesoscopic transport phenomena in structured semiconductor inversion layers. In addition, some of the most recent achievements are reported in contributed papers. The aim of the volume is not to give an overview over the field. Instead, emphasis is on interaction and correlation phenomena that turn out to be of increasing importance for the understanding of the phenomena in the quantum Hall regime, and in the transport through quantum dots. The present status of the quantum Hall experiments and theory is reviewed. As a "key example" for non-Fermi liquid behavior the Luttinger liquid is introduced, including some of the most recent developments. It is not only of importance for the fractional quantum Hall effect, but also for the understanding of transport in quantum wires. Furthermore, the chaotic and the correlation aspects of the transport in quantum dot systems are described. The status of the experimental work in the area of persistent currents in semiconductor systems is outlined. The construction of one of the first single-electron transistors is reported. The theoretical approach to mesoscopic transport, presently a most active area, is treated, and some aspects of time-dependent transport phenomena are also discussed.

This book was released on 2013-03-01 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces researchers and students to the physical principles which govern the operation of solid-state devices whose overall length is smaller than the electron mean free path. In quantum systems such as these, electron wave behavior prevails, and transport properties must be assessed by calculating transmission amplitudes rather than microscopic conductivity. Emphasis is placed on detailing the physical laws that apply under these circumstances, and on giving a clear account of the most important phenomena. The coverage is comprehensive, with mathematics and theoretical material systematically kept at the most accessible level. The various physical effects are clearly differentiated, ranging from transmission formalism to the Coulomb blockade effect and current noise fluctuations. Practical exercises and solutions have also been included to facilitate the reader's understanding.

This book was released on 2017 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topic of the present thesis is: transport through mesoscopic systems. Mesoscopic systems are materials with a maximum size of the order of the micrometer, whose properties are governed by quantum mechanics. In these materials, the single and few particle transport dynamics, interactions and coherence are studied. The platforms considered for the development of the present thesis are quantum dots, where particles with a defined spin are confined in discrete energy levels. Different quantum dots are coupled by tunnel junctions, overlapping the wave functions of their higher energy states. The particles in these states are then coherently delocalized along the whole quantum dot structure, which behaves as an artificial molecule. A strong particle-particle interaction is present in these systems due to the short distant between them. These systems can be externally controlled by tunning gate voltages capacitively coupled to the dots; therefore, the energy, entropy, and the coherent dynamics of the systems change in a supervised manner. Most of the thesis is based in triple quantum dots, which constitute a perfect device to investigate multilevel quantum interference. They have the advantage of an spatial separation of the states that, with the recent advances in their tunability, makes it possible to manipulate them individually; on the other hand, the tunnel coupling between them can also be controlled. To study particle transport, the quantum dot systems are weakly coupled to reservoirs, with whom they exchange particles and energy. In Chapter 7 a triple quantum dot with three reservoirs is studied to demonstrate the interactions of the different transport paths between the reservoirs. The Coulomb interaction of the electrons and the correlations between the different paths leads to a current blocking in one of the channels when the other has high conductance...
