Beschreibung
The discoveries of the quantized Hall phenomenon and the quantum Hall effect during the early 1980s have had a profound impact on science and technology-redefining the resistance standard and spurring breakthrough innovations in many areas, including condensed-matter and solid-state physics, low-temperature physics, semiconductor materials science and devices, metrology, and quantum-field theory. This volume covers key experimental and theoretical developments in quantum Hall phenomena, focusing on the exciting developments of the past decade-a period that saw the field transform into one of physics' most prolific and dynamic research areas. The book offers important new insights into the fractional quantum Hall effect in low-dimensional systems of human-made quantum structures and discusses the quantum Hall effect as both a theoretical method for the study of semi-conductors and as a tool for physicists and electrical engineers working in the electronics industry. Written by top-notch researchers from across the field, this compilation of contributions consists of lucid and imaginative perspectives independent of the conventional review format. Theoretical and experimental issues are integrated throughout, and topics are carefully selected to reflect both the current state of the art and promising future trends. Each chapter is self-contained, complete with many useful references-providing a comprehensive and accessible treatment of the subject at hand. The various chapters cover the quantum Hall effect in relationship to localization and metal-insulator transitions, as well as multicomponent quantum Hall systems, properties of the electron solid, and edge state transport. A chapter is devoted to the Fermion Chern-Simons theory and the unquantized quantum Hall effect, and subsequent chapters discuss resonant inelastic light scattering from these systems, magnetic field-induced 2D Wigner crystal, and composite fermions in the fractional quantum Hall effect. Perspectives in Quantum Hall Effects is designed for graduate students and experienced researchers, for theorists and experimentalists alike, providing a thought-provoking reference for this rapidly growing field and a source of exciting new ideas for future research.
The discovery of the quantized and fractional Quantum Hall Effect phenomena is among the most important physics findings in the latter half of this century. The precise quantization of the electrical resistance involved in the quantized Hall effect phenomena has led to the new definition of the resistance standard and has metrologically affected all of science and technology. This resource consists of contributions from the top researchers in the field who present recent experimental and theoretical developments. Each chapter is self-contained and includes its own set of references guiding readers to original papers and further reading on the topic.
