Book excerpt: "Among the many materials investigated in the infrared (IR) field, narrow-gap semiconductors are the most important in IR photon detector family. Although the first widely used narrow-gap materials were lead salts (during the 1950s, IR detectors were built using single-element-cooled PbS and PbSe photoconductive detectors, primary for anti-missile seekers), this semiconductor family was not well distinguished. This situation seems to have resulted from two reasons: the preparation process of lead salt photoconductive polycrystalline detectors was not well understood and could only be reproduced with well-tried recipes; and the theory of narrow-gap semiconductor bandgap structure was not well known for correct interpretation of the measured transport and photoelectrical properties of these materials"--

Download or read book 2D Materials for Infrared and Terahertz Detectors written by Antoni Rogalski and published by CRC Press. This book was released on 2020-10-25 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2022-01-03 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wars may officially end and treaties may be signed, but their lethal legacy lives on in the form of unexploded ordinance and minefields that continue to harm civilian populations. Aerial reconnaissance reduces the need for risky, costly and time-consuming ground operations, and the rapid development of unmanned aerial vehicles offers crucial innovations for addressing the aftermath of conflicts worldwide. Aleksandar Smiljanic, an international recognized subject matter expert in next generation defence technologies, examines current developments in technology, electronics, and unmanned autonomous systems that are increasingly allowing military experts to address the challenges of mine clearance and left-over munitions, thereby helping to neutralize the dangers posed by former battlefields. Focusing on the role that unmanned vehicle reconnaissance can play in future identification and clearance operations, the author's timely and critical account - richly illustrated and with a host of supporting scientific and mathematical evidence throughout - offers a fertile and thought-provoking array of solutions to a scourge that has affected civilian populations and civic infrastructure throughout the world for decades. This is a must-read for political and military policymakers and a vital contribution to global efforts at humanitarian relief when it comes to rebuilding the social, political, economic, and cultural landscape of affected populations, with effects not just on their own countries but consequences for us all.

Download or read book Quaternary Capped In Ga As GaAs Quantum Dot Infrared Photodetectors written by Sourav Adhikary and published by Springer. This book was released on 2017-09-06 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces some alternative methods for enhancing the performance of In(Ga)As/GaAs-based quantum dot infrared photodetectors (QDIPs). In(Ga)As/GaAs-based QDIPs and focal plane array (FPA) cameras have wide application in fields such as military and space science. The core of the study uses a combination of quaternary In0.21Al0.21Ga0.58As and GaAs spacer as a capping layer on In(Ga)As/GaAs quantum dots in the active region of the detector structure. For the purposes of optimization, three types of samples growths are considered with different capping thicknesses. The results presented include TEM, XRD and photoluminescence studies that compare combination barrier thickness and its effect on structural and optical properties. Compressive strain within the heterostructure, thermal stability in high temperature annealing, spectral response, shifts in PL peaks peak,and responsivity and detectivity are all considered. The results also present a narrow spectral width that was obtained by using InAs QDs which is very useful for third generation FPA camera application. The book details effect of post-growth rapid thermal annealing on device characteristics and methods to enhance responsivity and peak detectivity. The contents of this book will be useful to researchers and professionals alike.
