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.

* Guides readers into more detailed and technical treatments of readout optical signals * Gives a broad overview of optical signal detection including terahertz region and two-dimensional material * Helps readers further their studies by offering chapter-end problems and recommended reading.

Currently, III-V antimonide-based detector technology is under strong development as a possible alternative to HgCdTe material systems. The apparent rapid success of a broken-gap type-II superlattice (T2SL) depends not only on the previous five decades of development of III-V materials, but mainly on recent ideas in the design of infrared photodetectors. The ability to tune the positions of the conduction and valence band edges independently in the T2SL is especially helpful in the design of unipolar barriers. Unipolar barriers are used to implement the barrier detector architecture for increasing the collection efficiency of photogenerated carriers and reducing dark current originating within the depletion region without inhibiting photocurrent flow. During the last decade, antimonide-based focal plane array technology has achieved a level close to HgCdTe. However, the modern version of the technology is still in its infancy. The advent of bandgap engineering has given III-Vs a new lease on life. This book describes current concepts of antimonide-based IR detectors, focusing on designs having the largest impact on the mainstream of IR detector technologies. It is suitable for graduate students in physics and engineering who have knowledge of modern solid-state physics and electronic circuits, and will be of interest to those working with aerospace sensors and systems, remote sensing, thermal imaging, military imaging, optical telecommunications, infrared spectroscopy, and lidar.
