Provides a basic understanding of how semiconductor quantum wells and superlattices can be used for long-wavelength infrared detectors and related systems. It represents a step towards a knowledge of novel structures that could be used for high-performance infrared detectors and imaging rays.

This timely work presents a comprehensive overview of the development of new generations of infrared detectors based on artificially synthesized quantum structures. The growth of quantum wells and superlattices is well documents in this volume, as are the principal new superlattice technologies for long wavelength infrared detection. Featuring insightful contributions from researchers working at the "cutting edge" of this exciting field, this volume is sure to become an essential reference for advanced graduate students and researchers alike.

This book offers a thorough survey of long wavelength infrared semiconductor emitters based primarily on quantum wells and superlattices. Featuring contributions from the most prominent researchers in the field, this volume allows readers to compare different types of lasers as well as examine investigations of potential far-infrared/terrahertz sources. This is an essential reference for researchers, engineers and graduate students who wish to obtain comprehensive knowledge about infrared semiconductor sources and recent developments in this field.

This book is unique in that it combines for the first time the infrared detectors and infrared lasers and emitters in one volume. It is merely a step, however, in a very fast-changing field, toward achieving an understanding of novel structures that can be used for high-performance infrared detectors, imaging arrays, infrared lasers and sources. Internationally-known experts discuss recent advances in materials structures, processing and device performances, with presentations crossing materials and discipline boundaries. Recent investigations based on III-V, II-VI and IV bulk semiconductors, quantum wells, and superlattices for long-wavelength infrared detectors, emitters, sources and materials are featured. Topics include: antimonide-related materials and devices; quantum wells and devices; quantum infrared detectors; HgCdTe - materials, devices and processing; nonlinear and parametric oscillator material; interdiffusion in heterostructures and related topics.

Completely revised and reorganized while retaining the approachable style of the first edition, Infrared Detectors, Second Edition addresses the latest developments in the science and technology of infrared (IR) detection. Antoni Rogalski, an internationally recognized pioneer in the field, covers the comprehensive range of subjects necessary to un

The focus of the workshop was on innovative long wavelength infrared (LWIR) detectors with the potential of meeting future NASA and DoD long duration space application needs. Requirements are for focal plane arrays which operate near 65K using active refrigeration with mission lifetimes of five to ten years. The workshop addressed innovative concepts, new material systems, novel device physics, and current progress in relation to benchmark technology. It also provided a forum for discussion of performance characterization, producability, reliability, and fundamental limitations of device physics. It covered the status of the incumbent HgCdTe technology, which shows encouraging progress towards LWIR arrays, and provided a snapshot of research and development in several new contender technologies. These contenders span quantum wells, heterojunctions, and superlattices in columns 2-6, 3-5 and 4 semiconductor materials and promise producible LWIR arrays with the required performance. The workshop also included a session on new innovations for high performance thermal detectors.

Long-wavelength Infrared Semiconductor Lasers provides a comprehensive review of the current status of semiconductor coherent sources emitting in the mid-to far-infrared spectrum and their applications. It includes three topics not covered in any previous book: far-infrared emission from photo-mixers as well as from hot-hole lasers, and InP-based lasers emitting beyond two micrometers. Semiconductor lasers emitting at more than two micrometers have many applications such as in trace gas analysis, environmental monitoring, and industrial process control. Because of very rapid progress in recent years, until this book no comprehensive information beyond scattered journal articles is available at present.
