Download or read book Theory of Quantum Transport at Nanoscale written by Dmitry Ryndyk and published by Springer. This book was released on 2015-12-08 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to a rapidly developing field of modern theoretical physics – the theory of quantum transport at nanoscale. The theoretical methods considered in the book are in the basis of our understanding of charge, spin and heat transport in nanostructures and nanostructured materials and are widely used in nanoelectronics, molecular electronics, spin-dependent electronics (spintronics) and bio-electronics. The book is based on lectures for graduate and post-graduate students at the University of Regensburg and the Technische Universität Dresden (TU Dresden). The first part is devoted to the basic concepts of quantum transport: Landauer-Büttiker method and matrix Green function formalism for coherent transport, Tunneling (Transfer) Hamiltonian and master equation methods for tunneling, Coulomb blockade, vibrons and polarons. The results in this part are obtained as possible without sophisticated techniques, such as nonequilibrium Green functions, which are considered in detail in the second part. A general introduction into the nonequilibrium Green function theory is given. The approach based on the equation-of-motion technique, as well as more sophisticated one based on the Dyson-Keldysh diagrammatic technique are presented. The main attention is paid to the theoretical methods able to describe the nonequilibrium (at finite voltage) electron transport through interacting nanosystems, specifically the correlation effects due to electron-electron and electron-vibron interactions.

Available in PDF, EPUB and Kindle. Book excerpt: The quantum transport theory, which dates back to the time of the Landauer theory in the field of mesoscopic physics, is now expanding its power on materials science and chemistry by earning chemical accuracy and physical reality and has become a new subject of non-equilibrium quantum transport theory for charge and heat at nanoscale. This growing subject invites cross-disciplinary developments, for example, the local heating theory developed earlier was examined and applied to the self-heating problem in the field of semiconductor- and nanoelectronic-device physics. This book compiles 25 key published papers to provide readers with convenient and comprehensive access to the important results and developments in the field. The book will appeal to a wide range of readers from varied backgrounds, especially those involved in charge- and/or heat-transport problems that widely spread over various subjects in materials science, chemistry, electric engineering, and condensed matter physics.
Download or read book Electron Transport in Nanostructures and Mesoscopic Devices written by Thierry Ouisse and published by John Wiley & Sons. 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 2011 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: One-dimensional (1D) electronic nanostructures comprise a class of systems that boast tremendous promise for both technological innovation as well as fundamental scientific discovery. To fully harness their potential, it is crucial to understand transport through 1D systems at the most fundamental, quantum level. In this thesis, we describe our investigations down three avenues of quantum transport in 1D: (1) ballistic transport in quantum wires, (2) quantum capacitance measurements of nanostructures, and (3) tunneling measurements in carbon nanotubes. First, we discuss measurements and modeling of hole transport in ballistic quantum wires fabricated by GaAs/AlGaAs cleaved-edge overgrowth, where we find strong g-factor anisotropy, which we associate with spin-orbit coupling, and evidence for the importance of charge interactions, indicated by the observation of "0.7" structure. Additionally, we present the first experimental observation of a predicted spin-orbit gap in the 1D density of states, where counter-propagating spins constituting a spin current are accompanied by a clear signal in the conductance. Next, we present the development of a highly sensitive integrated capacitance bridge for quantum capacitance measurements to be used as a novel probe of 1D systems. We demonstrate the utility of our bridge by measuring the capacitance of top-gated graphene devices, where we cleanly resolve the density of states, and also present preliminary measurements of carbon nanotube devices, where we ultimately aim to extract their mobility. Finally, we discuss a set of transport measurements in carbon nanotubes designed to probe interactions between fermions in 1D in which top gates are used to introduce tunable tunnel barriers.

Download or read book Advanced Physics of Electron Transport in Semiconductors and Nanostructures written by Massimo V. Fischetti and published by Springer. This book was released on 2016-05-20 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is aimed at second-year graduate students in Physics, Electrical Engineering, or Materials Science. It presents a rigorous introduction to electronic transport in solids, especially at the nanometer scale.Understanding electronic transport in solids requires some basic knowledge of Hamiltonian Classical Mechanics, Quantum Mechanics, Condensed Matter Theory, and Statistical Mechanics. Hence, this book discusses those sub-topics which are required to deal with electronic transport in a single, self-contained course. This will be useful for students who intend to work in academia or the nano/ micro-electronics industry.Further topics covered include: the theory of energy bands in crystals, of second quantization and elementary excitations in solids, of the dielectric properties of semiconductors with an emphasis on dielectric screening and coupled interfacial modes, of electron scattering with phonons, plasmons, electrons and photons, of the derivation of transport equations in semiconductors and semiconductor nanostructures somewhat at the quantum level, but mainly at the semi-classical level. The text presents examples relevant to current research, thus not only about Si, but also about III-V compound semiconductors, nanowires, graphene and graphene nanoribbons. In particular, the text gives major emphasis to plane-wave methods applied to the electronic structure of solids, both DFT and empirical pseudopotentials, always paying attention to their effects on electronic transport and its numerical treatment. The core of the text is electronic transport, with ample discussions of the transport equations derived both in the quantum picture (the Liouville-von Neumann equation) and semi-classically (the Boltzmann transport equation, BTE). An advanced chapter, Chapter 18, is strictly related to the ‘tricky’ transition from the time-reversible Liouville-von Neumann equation to the time-irreversible Green’s functions, to the density-matrix formalism and, classically, to the Boltzmann transport equation. Finally, several methods for solving the BTE are also reviewed, including the method of moments, iterative methods, direct matrix inversion, Cellular Automata and Monte Carlo. Four appendices complete the text.

Book excerpt: The developments of nanofabrication in the past years have enabled the design of electronic systems that exhibit spectacular signatures of quantum coherence. Nanofabricated quantum wires and dots containing a small number of electrons are ideal experimental playgrounds for probing electron-electron interactions and their interplay with disorder. Going down to even smaller scales, molecules such as carbon nanotubes, fullerenes or hydrogen molecules can now be inserted in nanocircuits. Measurements of transport through a single chain of atoms have been performed as well. Much progress has also been made in the design and fabrication of superconducting and hybrid nanostructures, be they normal/superconductor or ferromagnetic/superconductor. Quantum coherence is then no longer that of individual electronic states, but rather that of a superconducting wavefunction of a macroscopic number of Cooper pairs condensed in the same quantum mechanical state. Beyond the study of linear response regime, the physics of non-equilibrium transport (including non-linear transport, rectification of a high frequency electric field as well as shot noise) has received much attention, with significant experimental and theoretical insights. All these quantities exhibit very specific signatures of the quantum nature of transport, which cannot be obtained from basic conductance measurements. Basic concepts and analytical tools needed to understand this new physics are presented in a series of theoretical fundamental courses, in parallel with more phenomenological ones where physics is discussed in a less formal way and illustrated by many experiments.· Electron-electron interactions in one-dimensional quantum transport· Coulomb Blockade and Kondo physics in quantum dots· Out of equilibrium noise and quantum transport· Andreev reflection and subgap nonlinear transport in hybrid N/S nanosructures.· Transport through atomic contacts · Solid state Q-bits · Written by leading experts in the field, both theorists and experimentalists
