Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor Quantum Well Intermixing is an international collection of research results dealing with several aspects of the diffused quantum well (DFQW), ranging from Physics to materials and device applications. The material covered is the basic interdiffusion mechanisms of both cation and anion groups as well as the properties of band structure modifiations. Its comprehensive coverage of growth and pos-growth processing technologies along with its presentation of the various interesting and advanced features of the DFQW materials make this book an essential reference to the study of QW layer intermixing.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The wide variety of applications for mid- and far-infrared detection has spurred the study of cutting-edge technologies for use in the next genera- tion of detectors in place of the current systems, such as mercury cadmium telluride. While type-II superlattices over a number of advantages in design and material quality, theoretical predictions of their high performance have yet to be realized. This work concentrates on novel designs, fabrication, and characterization of type-II superlattice infrared detectors. In this work we present the first InAs/GaSb type-II superlattice photode- tectors grown on an InAs substrate via metal-organic chemical vapor depo- sition. The design and fabrication of the devices are detailed, along with several characterization processes, including low-temperature electron beam induced current (EBIC) to study structural defects. Through this work, the optical absorption of the undoped substrate was shown to be significantly lower than that of GaSb. The detectors have a cutoff wavelength (50% re- sponsivity) of 9.5 um at 78 K. Their R0A values are on the order of 10^-2 Ohm*cm2. The typical peak responsivity is 1.9 A/W, and the devices have a peak detectivity of 6.8 * 10^9 cm*Hz^1/2 /W at 78 K.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Three quantum well infrared photodetectors are characterized utilizing noise spectral density and current-voltage measurements taken at a variety of temperatures and biases. Though all devices were fabricated using the GaAs/InGaAs material system, each has a unique morphology. D1 had three different quantum wells per period and 20 periods. D2 had one type of quantum well and 10 periods. D3 had one type of quantum well, 5 periods, and asymmetric barriers. Measurement temperatures for D1 ranged between 80 K and 180 K with bias values for each temperature between zero and 35 mA. For D2 and D3 measurement temperatures ranged between 80 K and 125 K with bias values for each temperature between zero and 10 mA. Utilizing models for thermionic emission current and Fowler-Nordheim tunneling current the current-voltage characteristic of each device was compared with the theory. The thermionic emission model did well for all devices at low bias. The tunneling model did well for all devices at high bias. In the middle range of biases D1 was underestimated by the models, D3 was overestimated by the models, and D2 was modeled well by a sum of the two models.

This book was released on 2018-04-04 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atomic thin two-dimensional (2D) materials are the thinnest forms of materials to ever occur in nature and have the potential to dramatically alter and revolutionize our material world. Some of the unique properties of these materials including wide photoresponse wavelength, passivated surfaces, strong interaction with incident light, and high mobility have created tremendous interest in photodetector application. This book provides a comprehensive state-of-the-art knowledge about photodetector technology in the range visible to infrared region using various 2D materials including graphene, transition metal dichalcogenides, III-V semiconductor, and so on. It consists of 10 chapters contributed by a team of experts in this exciting field. We believe that this book will provide new opportunities and guidance for the development of next-generation 2D photodetector.
