Taschenbuch. Zustand: Neu. Neuware - This book is intended for readers desiring a comprehensive analysis of the latest developments in widegap II-VI materials research for opto-electronic applications and basic insight into the fundamental underlying principles. Therefore, it is hoped that this book will serve two purposes. Firstly, to educate newcomers to this exciting area of physics and technology and, secondly, to provide specialists with useful references and new insights in related areas of II-VI materials research. The motivation for preparing this book originated from the need for a current review of this fertile and important field. A primary goal of this book is therefore to present an eclectic synthesis of these sometimes diverse fields of investigation. This book consists of three main sections, namely (1) Growth and Properties, (2) Materials Characterization and (3) Devices. Part One presents an overall perspective of the state of the art in the preparation of the widegap II-VI materials. Part Two concentrates on current topics pertinent to the characterization of these materials from the unique perspective of each of the authors. Part Three focuses on advances in the opto-electronic applications of these materials. The material in this section runs the gamut from addressing recent advances in device areas which date back to some of the earliest reported research in these materials, to tackling some quite new and exciting future directions.…

Taschenbuch. Zustand: Neu. Neuware - Controlling the mechanical, electrical, magnetic, and optical properties of materials by advanced fabrication methods (Le. ; Molecular Beam Epitaxy and Metal-Organic Chemical Vapor Deposition) has become the new paradigm in our research era. Sensors, being the most vital part of the electronic data processing and decision making machines, stand to gain the most from engineering of the properties of materials. Microfabrication technology has already contributed significantly to the batch fabrication of micro-sensors with higher over all qualities compared to their counterparts that are fabricated using other methods. Batch fabrication of micro-sensors i) results in more uniform properties of co-fabricated devices, ii) nearly eliminates the need for characterization of individual sensors, and iii) eliminates a need for laborious alignment procedures. A less obvious benefit of using microfabrication methods is the possibility of precise control over the dimensions of the sensor. This control enables engineering of some of the properties of the material which affect the sensor's operation. There are many examples of this in the literature. Optical sensors are known to have superior properties over their counterparts that use other (i. e. ; electrostatic and magnetic) means of detection. To name a few, these advantages are: i) immunity to electromagnetic interferences, ii) higher sensitivities compared to the other types of sensors, iii) simplicity of operation principles, and iv) simplicity of overall construction.…

Taschenbuch. Zustand: Neu. Neuware - Electro-optic devices based on doped wide-band materials are present in industrial uses, in military applications and in everyday life. Whether one engages in laser surgery with a neodymium-Y AG laser or one communicates overseas using optical fibers, the development of these materials is both scientifically and commercially of great interest. Much of the most innovative work has been done in the last 15 years in this area. A minor revolution in optical fiber communications has occurred with the development of erbium-doped fiber amplifiers. Solid-state laser development shifted into high-gear with the theoretical and experimental study of doubly-doped garnet lasers. Recent developments on semiconductor laser arrays are making diode pumped solid-state lasers commercially feasible. The purpose of this book is to detail these developments and to point out that many of the same underlying physical processes control advances in several diverse applications. For example, the basic science of energy transfer will be discussed by Zharikov et al. and Rotman for energy transfer and dopant-defect interactions, respectively; it will also be crucial in understanding cerium-doped scintilla tors, neodymium-chromium lasers, and up-conversion fiber lasers. As another example, phonon-induced non-radiative relaxation will appear in every chapter in this book.…
