Book Description
"Strained-layer superlattices (SLS) are a type of meta-material which exhibit tunable properties and are expected to provide a host of benefits for infrared (IR) photodetectors, most notably an arbitrarily long cutoff wavelength. This represents an opportunity for III-V absorber materials to be extended into mid-wave infrared (MWIR) and long-wave infrared (LWIR) applications. However, noise measurements remain too high in these IR photodetectors for SLS absorbers to be competitive with current MWIR and LWIR technologies. One of the major contributors to noise is surface leakage, where electrical conduction occurs along exposed semiconductor surfaces. While surface leakage occurs even in relatively large detector devices, the detrimental effects will be exacerbated as detector size decreases, and therefore the relative surface area and conduction pathways of surface leakage increases. An investigation into the surface characteristics of SLS structures through modeling, growth, processing, and characterization will be discussed. The outcome of this investigation is a greater understanding of the physical mechanism of surface currents in SLS structures, and an IR photodetector design which utilizes the unipolar barrier architecture to suppress all surface leakage currents, and therefore reduce noise to competitive levels."--Page x.

Book Description
The following blurb to be used for the AP Report and ATI only as both volumes will not appear together there.****Strained-layer superlattices have been developed as an important new form of semiconducting material with applications in integrated electro-optics and electronics. Edited by a pioneer in the field, Thomas Pearsall, this volume offers a comprehensive discussion of strained-layer superlattices and focuses on fabrication technology and applications of the material. This volume combines with Volume 32, Strained-Layer Superlattices: Physics, in this series to cover a broad spectrum of topics, including molecular beam epitaxy, quantum wells and superlattices, strain-effects in semiconductors, optical and electrical properties of semiconductors, and semiconductor devices.****The following previously approved blurb is to be used in all other direct mail and advertising as both volumes will be promoted together.****Strained-layer superlattices have been developed as an important new form of semiconducting material with applications in integrated electro-optics and electronics. Edited by a pioneer in the field, Thomas Pearsall, this two-volume survey offers a comprehensive discussion of the physics of strained-layer superlattices (Volume 32), as well as detailing fabrication technology and applications of the material (Volume 33). Although each volume is edited to stand alone, the two books combine to cover a broad spectrum of topics, including molecular beam epitaxy, quantum wells and superlattices, strain-effects in semiconductors, optical and electrical properties of semiconductors, and semiconductor devices.

Book Description
Devices built from three-dimensional nanoarchitectures offer a number of advantages over those based on thin-film technology, such as larger surface area to enhance the sensitivity of sensors, to collect more sunlight to improve the efficiency of solar cells, and to supply higher density emitters for increased resolution in flat panel displays. Three-dimensional nanoscale assembly has already been used to generate many prototypes of devices and sensors, including piezoelectric nanogenerators based on ZnO nanowire arrays, photovoltaic devices based on silicon nanowire array p-n junctions, and highly sensitive gas sensors based on metal oxide nanowire arrays among others. Three-Dimensional Nanoarchitectures: Designing Next-Generation Devices describes state-of-the-art synthesis, integration, and design strategies used to create three-dimensional nanoarchitectures for functional nanodevice applications. With a focus on synthesis and fabrication methods for three-dimensional nanostructure assembly and construction, coverage includes resonators, nanophotonics, sensors, supercapacitors, solar cells, and more. This book is an essential reference for a broad audience of researchers in materials science, chemistry, physics, and electrical engineering who want the latest information on synthesis routes and assembly methods. Schematics of device integration and mechanisms as well as plots of measurement data are included.
