The theoretical understanding of transport properties of semiconductor structures on short length and short time scales, and in the nonlinear high-field regime is of particular relevance for future electronic and optoelectronic materials. In recent years great progress has been made in a variety of aspects. Theory of Transport Properties of Semiconductor Nanostructures presents a state-of-the-art overview of theoretical methods, results, and applications in the field. It contains eleven chapters which are written by leading researchers. This book starts with a tutorial introduction to the subject, then in the following five chapters a hierarchy of different approaches to transport theory is presented, descending from a macroscopic level (quasihydrodynamic simulation) via semiclassical Monte Carlo techniques and cellular automata to a full quantum transport theory covering both Green's functions and density matrix theory. In the last five chapters the formalism is applied to more specific topics which are of great current interest such as transport in mesoscopic structures, chaotic dynamics in lateral superlattices, Bloch oscillations and Wannier-Stark localization, field domain formation in superlattices, and scattering processes in low-dimensional structures. Theory of Transport Properties of Semiconductor Nanostructures is aimed at physicists, electronic engineers, materials scientists and applied mathematicians. It may be used in research, as a professional reference in microelectronics, optoelectronics, and graduate teaching. This book should be useful not only to graduate students but also to professional scientists working in the field. It attempts to present comprehensive reviewsof the most important advances, and often takes a tutorial approach.

The book summarizes the state-of-the-art of research on control of self-organizing nonlinear systems with contributions from leading international experts in the field. The first focus concerns recent methodological developments including control of networks and of noisy and time-delayed systems. As a second focus, the book features emerging concepts of application including control of quantum systems, soft condensed matter, and biological systems. Special topics reflecting the active research in the field are the analysis and control of chimera states in classical networks and in quantum systems, the mathematical treatment of multiscale systems, the control of colloidal and quantum transport, the control of epidemics and of neural network dynamics.

Recent advances in the fabrication of semiconductors have created almost un limited possibilities to design structures on a nanometre scale with extraordinary electronic and optoelectronic properties. The theoretical understanding of elec trical transport in such nanostructures is of utmost importance for future device applications. This represents a challenging issue of today's basic research since it requires advanced theoretical techniques to cope with the quantum limit of charge transport, ultrafast carrier dynamics and strongly nonlinear high-field ef fects. This book, which appears in the electronic materials series, presents an over view of the theoretical background and recent developments in the theory of electrical transport in semiconductor nanostructures. It contains 11 chapters which are written by experts in their fields. Starting with a tutorial introduction to the subject in Chapter 1, it proceeds to present different approaches to transport theory. The semiclassical Boltzmann transport equation is in the centre of the next three chapters. Hydrodynamic moment equations (Chapter 2), Monte Carlo techniques (Chapter 3) and the cellular au tomaton approach (Chapter 4) are introduced and illustrated with applications to nanometre structures and device simulation. A full quantum-transport theory covering the Kubo formalism and nonequilibrium Green's functions (Chapter 5) as well as the density matrix theory (Chapter 6) is then presented.

Semiconductors can exhibit electrical instabilities like current runaway, threshold switching, current filamentation, or oscillations, when they are driven far from thermodynamic equilibrium. This book presents a coherent theoretical des- cription of such cooperative phenomena induced by generation and recombination processes of charge carriers in semicon- ductors.

Nonlinear transport phenomena are an increasingly important aspect of modern semiconductor research. This volume deals with complex nonlinear dynamics, pattern formation, and chaotic behavior in such systems. It bridges the gap between two well-established fields: the theory of dynamic systems and nonlinear charge transport in semiconductors. This unified approach helps reveal important electronic transport instabilities. The initial chapters lay a general framework for the theoretical description of nonlinear self-organized spatio-temporal patterns, such as current filaments, field domains, fronts, and analysis of their stability. Later chapters consider important model systems in detail: impact ionization induced impurity breakdown, Hall instabilities, superlattices, and low-dimensional structures. State-of-the-art results include chaos control, spatio-temporal chaos, multistability, pattern selection, activator-inhibitor kinetics, and global coupling, linking fundamental issues to electronic device applications. This book will be of great value to semiconductor physicists and nonlinear scientists alike.
