Book excerpt: Heavily doped n-type single crystals of GaN were grown epitaxially by the vapor phase reaction of GaCl and NH3 on Sapphire substrates. GaN is a direct gap semiconductor with a bandgap of 3.25eV. It fluoresces efficiently in the visible as well as the UV. Single crystals of AlP were prepared by the disproportionation of gaseous AlI in the presence of PH3 either as freely nucleated whiskers or epitaxially on GaAs or Si substrates. Attempts to determine the mechanisms of the efficient Cu green luminescence in ZnS and the mechanism responsible for room temperature lasing in CdS were unsuccessful. In order to design semiconductor alloy systems to achieve high efficiency luminescence in the visible, the authors have observed the effects of alloying small amounts of InP and AlP with GaP on the luminescence of GaP.

The first part covers the general background and theory of radiation effects in crystals, including the theory describing the generation of crystal lattice defects by radiation, the kinetic approach to the study of the disposition of these defects and the effects of the diffusion of these defects on alloy compositions and phases. Specific problems of current interest are treated in the second part and include anisotropic dimensional changes in x-uranium, zirconium and graphite, acceleration of thermal creep in reactor materials, and radiation damage of semiconductors and superconductors.

Download or read book Effects of Radiation on Semiconductors written by Viktor S. Vavilov and published by Springer. This book was released on 2013-12-14 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of electromagnetic radiation and high-energy par ticles on semiconductors can be divided into two main processes: (a) the excitation of electrons (the special case is internal ioniza tion, i. e. , the generation of excess charge carriers); and(b) dis turbance of the periodic structure of the crystal, i. e. , the forma tion of "structural radiation defects. " Naturally, investigations of the effects of radiation on semiconductors cannot be considered in isolation. Thus, for example, the problern of "radiation de fects" is part of the generalproblern of crystal lattice defects and the influence of such defects on the processes occurring in semi conductors. The same is true of photoelectric and similar phe nomena where the action of the radiation is only the start of a complex chain of nonequilibrium electronprocesses. Nevertheless, particularly from the point of view of the experimental physicist, the radiation effects discussed in the present book have inter esting features: several types of radiation may produce the same resul t (for example, ionization by photons and by charged particles) or one type of radiation may produce several effects (ionization and radiation -defect formation). The aim of the author was to consider the most typical prob lems. The subjects discussed differ widely from one another in the extent to which they have been investigated.

Download or read book Point Defects in Solids written by James H. Crawford and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 1 of Point Defects in Solids has as its major emphasis defects in ionic solids. Volume 2 now extends this emphasis to semiconductors. The first four chapters treat in some detail the creation, kinetic behavior, inter actions, and physical properties of both simple and composite defects in a variety of semiconducting systems. Also included, as in Vol. 1, are chapters on special topics, namely phonon-defect interactions and defects in organic crystals. Defect behavior in semiconductors has been a subject of considerable interest since the discovery some twenty-five years ago that fast neutron irradiation profoundly affected the electrical characteristics of germanium and silicon. Present-day interest has been stimulated by such semiconductor applications as solar cell power plants for space stations and satellites and semiconductor particle and y-ray detectors, since in both radiation damage can cause serious deterioration. Of even greater practical concern is the need to understand particle damage in order to capitalize upon the develop ing technique of ion implantation as a means of device fabrication. Although the periodic international conferences on radiation effects in semiconductors have served the valuable function of summarizing the extensive work being done in this field, these proceedings are much too detailed and lack the background discussion needed to make them useful to the novice.

Download or read book Exciton and Domain Luminescence of Semiconductors written by N. G. Basov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, which comprises a collection of papers by leading Soviet researchers, is devoted to topics in the luminescence of semiconductors. An experimental check is made on a series of predictions of the theory of ionization domains. A new low-voltage luminescence of zinc sulfide is described and investigated and is found to be due to a high-frequency electrical instability. A detailed study of the electrical properties of the instability and of the characteristics of the emission testifies to the pre-breakdown character of the electroluminescence and to the acousto electrical nature of the instability. The luminescence excitation spectra of AIN crystals excited in the region of the fundamental absorption contain lines belonging to excitons and their phonon replicas. The symmetry of the electronic and vibrational transitions corresponding to parts of these lines is interpreted. The results of a study of the scattering of light by electron - hole drops in germanium are cited. The results are discussed on the basis of a theory of exciton condensation in which allowance is made for the diffusion of excitons toward the surface of the drops and for the surface tens ion of the electron - hole liquid. This volume will be of interest to a wide range of scientific workers, particularly those engaged in the study of luminescence and physics of semiconductors.

Download or read book Semiconductors and the Information Revolution written by John W. Orton and published by Academic Press. This book was released on 2009-06-17 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors and the Information Revolution sets out to explain the development of modern electronic systems and devices from the viewpoint of the semiconductor materials (germanium, silicon, gallium arsenide and many others) which made them possible. It covers the scientific understanding of these materials and its intimate relationship with their technology and many applications. It began with Michael Faraday, took off in a big way with the invention of the transistor at Bell Labs in 1947 and is still burgeoning today. It is a story to match any artistic or engineering achievement of man and this is the first time it has been presented in a style suited to the non-specialist. It is written in a lively, non-mathematical style which brings out the excitement of discovery and the fascinating interplay between the demands of system pull and technological push. It also looks at the nature of some of the personal interactions which helped to shape the modern technological world. An introductory chapter illustrates just how dependent we are on modern electronic systems and explains the significance of semiconductors in their development. It also provides, in as painless a way as possible, a necessary understanding of semiconductor properties in relation to these applications. The second chapter takes up the historical account and ends with some important results emerging from the Second World War – including its effect on the organisation of scientific research. Chapter three describes the world-shaking discovery of the transistor and some of the early struggles to make it commercially viable, including the marketing of the first transistor radio. In chapter four we meet the integrated circuit which gave shape to much of our modern life in the form of the personal computer (and which gave rise to a famously long-running patent war!). Later chapters cover the application of compound semiconductors to light-emitting devices, such as LEDs and lasers, and light detecting devices such as photocells. We learn how these developments led to the invention of the CD player and DVD recorder, how other materials were applied to the development of sophisticated night vision equipment, fibre optical communications systems, solar photovoltaic panels and flat panel displays. Similarly, microwave techniques essential to our modern day love of mobile phoning are seen to depend on clever materials scientists who, not for the first time, "invented" new semiconductors with just the right properties. Altogether, it is an amazing story and one which deserves to be more widely known. Read this book and you will be rewarded with a much deeper understanding and appreciation of the technological revolution which shapes so many aspects of our lives. - A historical account of the development of semiconductor physics, devices and applications from the nineteenth century to the present day - Coverage of the importance of material quality and its relation to the physics of the devices - Presented in a strictly non-mathematical and anecedotal way, to appeal to a wide audience - Provides the broad sweep of science history
