Book Description
We have investigated novel semiconductor growth, materials, processes and devices. Gaseous source development for metalorganic molecular beam epitaxy (MOMBE) and metalorganic chemical vapor deposition (MOCVD) has been studied (Stillman). Silicon concentrations greater than 1 x 10(exp 19)/cu cm have been demonstrated using SiBr(4) by MOMBE and semi-insulating InP layers with resistivities greater than 1 x 10(exp 8) ohm-cm have been produced by using CCl(4) by MOCVD. High power and high perfomance semiconductor lasers and laser arrays have also been studied (Coleman). Several advanced processing techniques including reactive ion etching and e-beam lithography have been used to fabricate these lasers. In addition, the development of selective area epitaxy by MOCVD enables integration of lasers with electrical components for optoelectronic circuits on a single chip. Finally, use of inpurity induced layer disordering (IILD) and native oxides on high Al content compound semiconductors have been used to develop novel semiconductor laser devices (Holonyak). Microdisk lasers have been demonstrated using the IILD process to define curved geometry lasers. The native oxide has been used in vertical cavity surface emitting lasers VCSELs to define the current flow and to fabricate high-contrast distributed Bragg reflectors (DBRs).

Book Description
This volume provides valuable summaries on many aspects of advanced semiconductor heterostructures and highlights the great variety of semiconductor heterostructures that has emerged since their original conception. As exemplified by the chapters in this book, recent progress on advanced semiconductor heterostructures spans a truly remarkable range of scientific fields with an associated diversity of applications. Some of these applications will undoubtedly revolutionize critically important facets of modern technology. At the heart of these advances is the ability to design and control the properties of semiconductor devices on the nanoscale. As an example, the intersubband lasers discussed in this book have a broad range of previously unobtainable characteristics and associated applications as a result of the nanoscale dimensional control of the underlying semiconductor heterostructures. As this book illustrates, an astounding variety of heterostructures can be fabricated with current technology; the potentially widespread use of layered quantum dots fabricated with nanoscale precision in biological applications opens up exciting advances in medicine. In addition, many more excellent examples of the remarkable impact being made through the use of semiconductor heterostructures are given. The summaries in this volume provide timely insights into what we know now about selected areas of advanced semiconductor heterostructures and also provide foundations for further developments.

Book Description
Heterostructure and quantum-mechanical devices promise significant improvement in the performance of electronic and optoelectronic integrated circuits (ICs). Though these devices are the subject of a vigorous research effort, the current literature is often either highly technical or narrowly focused. This book presents heterostructure and quantum devices to the nonspecialist, especially electrical engineers working with high-performance semiconductor devices. It focuses on a broad base of technical applications using semiconductor physics theory to develop the next generation of electrical engineering devices. The text covers existing technologies and future possibilities within a common framework of high-performance devices, which will have a more immediate impact on advanced semiconductor physics-particularly quantum effects-and will thus form the basis for longer-term technology development.

Book Description
Heterostructures formed from III-V semiconductors with the 6.1 lattice spacing "InAs, GaSb, AlSb and related alloys" have attracted significant interest because of their potential to define a new 'state of the art' in applications including 100 GHz high-speed logic circuits, terahertz transistors, sensitive infrared detectors and mid-infrared semiconductor lasers. In this paper, we describe the ongoing work at the Naval Research Laboratory to develop the materials growth and fabrication technology for a variety of 6.1 -based devices that have the potential to revolutionize infrared optoelectronics and low-power high-speed electronics.
