State Of The Art Infrared Detector Technology

Scientists, engineers, managers, and policy makers who are currently involved in the funding of infrared R&D and subsequent system design and manufacture are confronted with a choice between two competing materials technologies, HgCdTe and III-V alloys. This book examines both the current and future performance of infrared focal plane arrays that use the various device architectures associated with these two materials technologies. All spectral bands from long wavelength (LWIR) through mid-wavelength (MWIR) to short wavelength (SWIR) are considered, ultimately with a view to achieving background and diffraction-limited system performance at room temperature for all wavelengths.

This book is about general infrared (IR) engineering, technology, practices, and principles as they apply to modem imaging systems. An alternative title to this book with appeal to managers and marketing personnel might be "Everything You Always Wanted to Know about Infrared Sensors, but Couldn't Get Answers on from Engineers." This book is not meant to be a comprehensive compendium of IR (like the Infrared and Electro Optical Systems Handbook). Rather, it is intend ed to complement such texts by providing up to date information and pragmatic knowledge that is difficult to locate outside of periodicals. The information contained in this book is critical in the day-to-day life of en gineering practitioners, proposal writers, and those on the periphery of an IR pro gram. It serves as a guide for engineers wishing to "catch up," engineers new to the field, managers, students, administrators, and technicians. It is also useful for seasoned IR engineers who want to review recent technological developments.

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

This volume is written for those who desire a comprehensive analysis of the latest developments in infrared detector technology and a basic insight into the fundamental processes which are important to evolving detection techniques. Each of the most salient infrared detector types is treated in detail by authors who are recognized as leading authorities in the specific areas addressed. In order to concentrate on pertinent aspects of the present state of the detector art and the unique point of view of each author, extensive tutorials of a background nature are avoided in the text but are readily available to the reader through the many references given. The volume opens with a broad-brush introduction to the various types of infrared detectors that have evolved since Sir William Herschel's discovery of infrared radiation 175 years ago. The second chapter presents an overall perspective of the infrared detector art and serves as the cohesive cement for the more in-depth presentation of subsequent chapters. Those detector types which, for one reason or other have not attained wide use today, are also discussed in Chapter 2. The more notable and widely used infrared detectors can be divided into three basic classes which are indicative of the primary effect produced by the photon-detector interaction, i.e., thermal, photoconductive, photo voltaic, and photoemissive. Chapters 3, 4, and 5 offer a detailed treatment of each of these important processes.

This new edition of Infrared and Terahertz Detectors provides a comprehensive overview of infrared and terahertz detector technology, from fundamental science to materials and fabrication techniques. It contains a complete overhaul of the contents including several new chapters and a new section on terahertz detectors and systems. It includes a new tutorial introduction to technical aspects that are fundamental for basic understanding. The other dedicated sections focus on thermal detectors, photon detectors, and focal plane arrays.

2D Materials for Infrared and Terahertz Detectors provides an overview of the performance of emerging detector materials, while also offering, for the first time, a comparison with traditional materials used in the fabrication of infrared and terahertz detectors. Since the discovery of graphene, its applications to electronic and optoelectronic devices have been intensively researched. The extraordinary electronic and optical properties allow graphene and other 2D materials to be promising candidates for infrared (IR) and terahertz (THz) photodetectors, and yet it appears that the development of new detectors using these materials is still secondary to those using traditional materials. This book explores this phenomenon, as well as the advantages and disadvantages of using 2D materials. Special attention is directed toward the identification of the most-effective hybrid 2D materials in infrared and terahertz detectors, as well as future trends. Written by one of the world’s leading researchers in the field of IR optoelectronics, this book will be a must-read for researchers and graduate students in photodetectors and related fields. Features • Offers a comprehensive overview of the different types of 2D materials used in fabrication of IR and THz detectors, and includes their advantages/disadvantages • The first book to compare new detectors to a wide family of common, commercially available detectors that use traditional materials.
