This book was released on 1982 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromium doped SI GaAs samples annealed at temperatures from 650 C to 950 C were examined for n-type thermal conversion. From Van der Pauw Hall measurements, it was determined that the samples annealed at 850 C, 900 C and 950 C thermally converted. These converted samples were then subjected to resistivity profile measurements to determine the extent of the thermally converted layer. Depth resolved photoluminescence was also used to observe changes in the spectra as surface layers from the converted samples were removed. Although changes in the spectra were observed, none could be related to thermal conversion. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The study of deep levels in semiconductors has seen considerable growth in recent years. Many new techniques have become available for investigating both the electronic properties of deep levels and the chemical nature of the defects from which they arise. This increasing interest has been stimulated by the importance of the subject to device technology, in particular those microwave and opto-electronic devices made from GaAs, InP and their alloys. While previous conferences have covered specialist areas of deep level technology, the meeting described here was arranged to draw together workers from these separate fields of study. The following papers reflect the breadth of interests represented at the conference. For the sake of uniformity we have chosen the English alternative where an American expression has been used. We have also sought to improve grammar, sometimes without the approval of the author in the interests of rapid publication. The Editor wishes to thank the referees for their ready advice at all stages, Paul Jay who helped with many of the editorial duties and Muriel Howes and Lorraine Jones for rapid and accurate typing.
Download or read book Atomic Diffusion in III V Semiconductors written by Brian Tuck and published by CRC Press. This book was released on 2021-05-31 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: III-V semiconductors, of which gallium arsenide is the best known, have been important for some years and appear set to become much more so in the future. They have principally contributed to two technologies: microwave devices and optoelectronics. Recent advances in the production of thin layers have made possible a whole new range of devices based on multi-quantum wells. The heat treatments used in the manufacture of semiconductor devices means that some diffusion must take place. A good understanding of diffusion processes is therefore essential to maintain control over the technology. Atomic Diffusion in III-V Semiconductors presents a lucid account of the experimental work that has been carried out on diffusion in III-Vs and explores the advanced models that explain the results. A review of the III-V group of semiconductors outlines the special properties that make them so attractive for some types of devices. Discussion of the basic elements of diffusion in semiconductors provides the theory necessary to understand the subject in depth, and the book gives hints on how to assess the published data. Chapters on diffusion of shallow donors, shallow acceptors, transition elements, and very fast-diffusing elements provide a critical review of published works. The book also presents the neglected subject of self-diffusion, including a section on superlattices. Atomic Diffusion in III-V Semiconductors will be of interest to research workers in semiconductor science and technology, and to postgraduate students in physics, electronics, and materials science.

This book was released on 2001-10-26 with total page 1915 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook brings together, under a single cover, all aspects of the chemistry, physics, and engineering of surfaces and interfaces of materials currently studied in academic and industrial research. It covers different experimental and theoretical aspects of surfaces and interfaces, their physical properties, and spectroscopic techniques that have been applied to a wide class of inorganic, organic, polymer, and biological materials. The diversified technological areas of surface science reflect the explosion of scientific information on surfaces and interfaces of materials and their spectroscopic characterization. The large volume of experimental data on chemistry, physics, and engineering aspects of materials surfaces and interfaces remains scattered in so many different periodicals, therefore this handbook compilation is needed.The information presented in this multivolume reference draws on two decades of pioneering research on the surfaces and interfaces of materials to offer a complete perspective on the topic. These five volumes-Surface and Interface Phenomena; Surface Characterization and Properties; Nanostructures, Micelles, and Colloids; Thin Films and Layers; Biointerfaces and Applications-provide multidisciplinary review chapters and summarize the current status of the field covering important scientific and technological developments made over past decades in surfaces and interfaces of materials and spectroscopic techniques with contributions from internationally recognized experts from all over the world. Fully cross-referenced, this book has clear, precise, and wide appeal as an essential reference source long due for the scientific community.
