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.

Continuing miniaturization of electronic devices, together with the quickly growing number of nanotechnological applications, demands a profound understanding of the underlying physics. Most of the fundamental problems of modern condensed matter physics involve various aspects of quantum transport and fluctuation phenomena at the nanoscale. In nanostructures, electrons are usually confined to a limited volume and interact with each other and lattice ions, simultaneously suffering multiple scattering events on impurities, barriers, surface imperfections, and other defects. Electron interaction with other degrees of freedom generally yields two major consequences, quantum dissipation and quantum decoherence. In other words, electrons can lose their energy and ability for quantum interference even at very low temperatures. These two different, but related, processes are at the heart of all quantum phenomena discussed in this book. This book presents copious details to facilitate the understanding of the basic physics behind a result and the learning to technically reproduce the result without delving into extra literature. The book subtly balances the description of theoretical methods and techniques and the display of the rich landscape of the physical phenomena that can be accessed by these methods. It is useful for a broad readership ranging from master’s and PhD students to postdocs and senior researchers.

The continuous miniaturization of electronic devices has given rise to structures whose dimensions do not exceed a few nanometers. At this size, electron transport can no longer be explained by simple drift and diffusion processes; electrons do not behave as point particles anymore but as propagating quantum-mechanical waves. In this thesis, we employ state-of-the-art quantum mechanical methods such as the non-equilibrium Green's functions and the density matrix method to study electron motion and light-matter interaction in nanostructures. We Will introduce new device functionalities that arise by tailoring two-dimensional materials such as graphene, phosphorene and transition-metal dichalcogenides (TMDs) into lower-dimensional nanostructures. In the first chapter we study electromagnetic field tuning of electronic properties of phosphorene and its nanoribbons. We show that by applying an electric field, phosphorene transitions from an insulator to a semimetal where a new type of quantum hall effect is observed. Later on, we show that near-equilibrium electron transport in metallic phosphorene nanoribbons takes place in the states whose wavefunctions are located near the edges of the ribbon. Electrical manipulation of these edge states provides a platform for the implementation of two different schemes of pseudospin electronics, a form of electronics based upon manipulation of tunable equivalents of the spin-one-half degree of freedom, i.e., the pseudospin. In chapter 2, we will introduce a numerically efficient density-matrix model applicable to midinfrared quantum cascade lasers. This model allows for inclusion of the lasing field and unlike previous models does not rely on phenomenologically introduced parameters. With the inclusion of lasing field a significant increase in the current density is observed, which leads to a better above-threshold agreement between the computed and experimental current density. In chapter 3, we study plasmon-enhanced optical non-linearity in low-dimensional nanostructures. We show that graphene nanomeshes and nanotriangles made of transition-metal dichalcogenides have great potential for applications in nonlinear nanophotonics. In particular, these nanostructures host plasmonic modes which can be easily excited and tuned for strong second- and third-harmonic generation.

The advent of semiconductor structures whose characteristic dimensions are smaller than the mean free path of carriers has led to the development of novel devices, and advances in theoretical understanding of mesoscopic systems or nanostructures. This book has been thoroughly revised and provides a much-needed update on the very latest experimental research into mesoscopic devices and develops a detailed theoretical framework for understanding their behaviour. Beginning with the key observable phenomena in nanostructures, the authors describe quantum confined systems, transmission in nanostructures, quantum dots, and single electron phenomena. Separate chapters are devoted to interference in diffusive transport, temperature decay of fluctuations, and non-equilibrium transport and nanodevices. Throughout the book, the authors interweave experimental results with the appropriate theoretical formalism. The book will be of great interest to graduate students taking courses in mesoscopic physics or nanoelectronics, and researchers working on semiconductor nanostructures.

When I was contacted by Kluwer Academic Publishers in the Fall of 200 I, inviting me to edit a volume of papers on the issue of electron transport in quantum dots, I was excited by what I saw as an ideal opportunity to provide an overview of a field of research that has made significant contributions in recent years, both to our understanding of fundamental physics, and to the development of novel nanoelectronic technologies. The need for such a volume seemed to be made more pressing by the fact that few comprehensive reviews of this topic have appeared in the literature, in spite of the vast activity in this area over the course of the last decade or so. With this motivation, I set out to try to compile a volume that would fairly reflect the wide range of opinions that has emerged in the study of electron transport in quantum dots. Indeed, there has been no effort on my part to ensure any consistency between the different chapters, since I would prefer that this volume instead serve as a useful forum for the debate of critical issues in this still developing field. In this matter, I have been assisted greatly by the excellent series of articles provided by the different authors, who are widely recognized as some of the leaders in this vital area of research.
