Book excerpt: This book is an account of the manner in which the optical phenomena observed from solids relate to their fundamental properties. Written at the graduate level, it attempts a threefold purpose: an indication of the breadth of the subject, an in-depth examination of important areas, and a text for a two-semester course. The first two chapters present introductory theory as a foundation for subsequent reading. The following ten chapters broadly concern electronic properties associated with semiconductors ranging from narrow to wide energy gap materials. Lattice properties are examined in the remaining chap ters, in which effects governed by phonons in perfect crystals, point defects, their vibrational and electronic spectra, and electron-phonon interactions are stressed. Fun and hard work, both in considerable measure, have gone into the preparation of this volume. At the University of Freiburg, W. Germany, from August 7-20, 1966, the occasion of a NATO Advanced Study Institute on "The Optical Properties of Solids," the authors of these various chapters lectured for the Institute; this volume provides essentially the "Proceed ings" of that meeting. Many major revisions of original lectures (contrac tions and enlargements) were required for better organization and presentation of the subject matter. Several abbreviated chapters appear mainly to indicate the importance of their contents in optical properties research and to indicate recently published books that provide ample coverage. We are indebted to many people: the authors for their efforts and patience; our host at the University of Freiburg, the late Professor Dr.

This book was released on 1987 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low temperature preparation of thin amorphous Silicon Nitride and Germanium Films by direct RF sputter deposition was investigated. Influence of various sputtering parameters on film properties was studied. Infrared transmission spectrophotometry was used to evaluate optical properties of the films whereas electrical characteristics of the films were determined from current-voltage measurements of MIS structures. For Silicon Nitride films it was observed that the stoichiometry, as indicated by the IR transmission, dielectric constant and current density versus square root of electric field measurements, was a strong function of the sputtering gas composition and particularly the Ar/N ratio in the sputtering gas. It was established from the current-voltage relationship that the dominant conduction mechanism in these films is of PooleFrenkel type. The current-voltage characteristics of the MIS devices were observed to be independent of the electrode material, device area and the film thickness. It is concluded that the insulating films thus deposited were comparable to those deposited using any other deposition method and is anticipated that due to the low deposition temperatures, sputtering may emerge as a highly potential process for optoelectronic device passivation.

The Electronic Properties Information Center (EPIC) is adesignated Information Analysis Center of the Department of Defense, authorized to provide information to the entire DoD community. The purpose of the Center is to provide a highly competent source of information and data on the electronic, optical and magnetic properties of materials of value to the Department of Defense. Its major function is to evaluate, compile and publish the experimental data from the world's unclassified literature concerned with the properties of materials. All materials relevant to the field of electronics are within the scope of EPIC: insulators, semiconductors, metals, super conductors, ferrites, ferroelectrics, ferromagnetics, electroluminescents, thermionic emitters and optical materials.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of the amorphous and glassy structure of amorphous germanium films on their electrical characteristics was investigated experimentally. The films were deposited onto silicon substrates using a modified MRC 8800 triode sputtering system. The Poole-Frenkel and Schottky mechanisms are discussed in detail and the shortcomings of the accepted picture of the former in amorphous materials are dealt with. It was concluded on the basis available evidence that the current flow in amorphous germanium favors the Poole-Frenkel mechanism at high fields. Amorphous hydrogenated germanium films which were deposited by bias sputtering were characterized by measuring the infrared absorption. The films have absorption peaks, as expected, at 1950 cḿ1 and at 570 cḿ1 due to GeH2 bonding and at 1880 cḿ1 due to GeH2 bonding. A method was described for determining the optical constants of a thin film deposited on a nonabsorbing window using a single set of transmittances over an absorption band. The method depends on the fact that the phase shift of the transmitted radiation can be determined from the transmittance by a Kramers-Kronig transform. The transmittance data of a-Ge:H and sputtered silicon nitride films were used to calculate their optical constants by this method. In a-Ge:H films, the value of the calculated refractive index in the k=0 region was not reasonable. However, for Si3N4 films, the calculated absorption coefficient was consistent with the experimental results.

Available in PDF, EPUB and Kindle. Book excerpt: The last quarter-century has been marked by the extremely rapid growth of the solid-state sciences. They include what is now the largest subfield of physics, and the materials engineering sciences have likewise flourished. And, playing an active role throughout this vast area of science and engineer ing have been very large numbers of chemists. Yet, even though the role of chemistry in the solid-state sciences has been a vital one and the solid-state sciences have, in turn, made enormous contributions to chemical thought, solid-state chemistry has not been recognized by the general body of chemists as a major subfield of chemistry. Solid-state chemistry is not even well defined as to content. Some, for example, would have it include only the quantum chemistry of solids and would reject thermodynamics and phase equilibria; this is nonsense. Solid-state chemistry has many facets, and one of the purposes of this Treatise is to help define the field. Perhaps the most general characteristic of solid-state chemistry, and one which helps differentiate it from solid-state physics, is its focus on the chemical composition and atomic configuration of real solids and on the relationship of composition and structure to the chemical and physical properties of the solid. Real solids are usually extremely complex and exhibit almost infinite variety in their compositional and structural features.
