Bismuth-containing compounds comprise a relatively unexplored materials system that is expected to offer many unique and desirable optoelectronic, thermoelectric, and electronic properties for innovative device applications. This book serves as a platform for knowledge sharing and dissemination of the latest advances in novel areas of bismuth-containing compounds for materials and devices, and provides a comprehensive introduction to those new to this growing field. Coverage of bismides includes theoretical considerations, epitaxial growth, characterization, and materials properties (optical, electrical, and structural). In addition to the well-studied area of highly mismatched Bi-alloys, the book covers emerging topics such as topological insulators and ferroelectric materials. Built upon fundamental science, the book is intended to stimulate interest in developing new classes of semiconductor and thermoelectric materials that exploit the properties of Bismuth. Application areas for bismide materials include laser diodes for optical communications, DVD systems, light-emitting diodes, solar cells, transistors, quantum well lasers, and spintronic devices.

The Workshop Heterostructure Epitaxy and Devices HEAD'97 was held from October 12 to 16, 1997 at Smolenice Castle, the House of Scientists of the Slovak Academy of Sciences and was co-organized by the Institute of Electrical Engineering, Slovak Academy of Sciences, Bratislava and the Institute of Thin Film and Ion Technology, Research Centre, liilich. It was the third in a series of workshops devoted to topics related to heterostructure epitaxy and devices and the second included into the category of Advanced Research Workshops (ARW) under sponsorship of the NATO. More than 70 participants from 15 countries attended (Austria, Belarus, Belgium, Czech Republic, Finland, Germany, Greece, Hungary, Italy, Poland, Russia, Slovakia, Ukraine, the United Kingdom and the USA). Novel microelectronic and optoelectronic devices are based on semiconductor heterostructures. The goal of the ARW HEAD'97 was to discuss various questions related to the use of new materials (e.g. compound semiconductors based on high band-gap nitrides and low band-gap antimonides) and new procedures (low-temperature epitaxial growth), as well as new principles (nanostructures, quantum wires and dots, etc.) aimed at realizing high-performance heterostructure based electronic devices. Almost 70 papers (invited and contributed oral presentations as well as posters) were presented at the ARW HEAD'97 and the main part of them is included into these Proceedings.

Revised and fully updated, the Second Edition of this textbook offers a comprehensive explanation of the technology and physics of light-emitting diodes (LEDs) such as infrared, visible-spectrum, ultraviolet, and white LEDs made from III–V semiconductors. The elementary properties of LEDs such as electrical and optical characteristics are reviewed, followed by the analysis of advanced device structures. With nine additional chapters, the treatment of LEDs has been vastly expanded, including new material on device packaging, reflectors, UV LEDs, III–V nitride materials, solid-state sources for illumination applications, and junction temperature. Radiative and non-radiative recombination dynamics, methods for improving light extraction, high-efficiency and high-power device designs, white-light emitters with wavelength-converting phosphor materials, optical reflectors, and spontaneous recombination in resonant-cavity structures, are discussed in detail. Fields related to solid-state lighting such as human vision, photometry, colorimetry, and color rendering are covered beyond the introductory level provided in the first edition. The applications of infrared and visible spectrum LEDs in silica fiber, plastic fiber, and free-space communication are also discussed. Semiconductor material data, device design data, and analytic formulae governing LED operation are provided. With exercises, solutions and illustrative examples, this textbook will be of interest to scientists and engineers working on LEDs, and to graduate students in electrical engineering, applied physics, and materials science.
