Quantum Electron Theory of Amorphous Conductors

The electron theory of solids has attracted great attention in recent years, mainly because of the numerous practical applications of semicon ductors. However, all the reviews and monographs on this subject deal only with crystalline conductors. At present, mainly in the Soviet Union, experi mental and theoretical investigations have been extended to liquid and solid amorphous conductors, and in particular to such semiconductors. However, all the work published so far in this field is in the form of separate papers scat tered throughout various journals, and there has as yet been no Soviet or for eign review of the theoretical work on amorphous semiconductors, in spite of the increasing interest in them. The investigation of liquid and amorphous semiconductors is of great practical importance, first, because all the solid semico'nductors are usually prepared from the liquid phase and it is important to know the electrical and other properties of this phase; secondly, amorphous semiconductors are beginning to be used in industry, for example, amorphous Sb S films in vidicon tubes. In some cases, especially in optical instruments, 2 S amorphous semiconductors have advantages compared with crystals. Theore tical studies of amorphous semiconductors should help in these practical applications. The present monograph is the first attempt to present systematically the quantum electron theory of amorphous conductors. The most interesting-in the author's view-theoretical papers on this subject, published in journals are reviewed and critically compared.

World Scientific Reference Of Amorphous Materials  The  Structure  Properties  Modeling And Main Applications  In 3 Volumes

Amorphous solids (including glassy and non-crystalline solids) are ubiquitous since the vast majority of solids naturally occurring in our world are amorphous. Although the field is diverse and complex, this three-volume set covers the vast majority of the important concepts needed to understand these materials and their principal practical applications. One volume discusses the most important subset of amorphous insulators, namely oxide glasses; the other two volumes discuss the most important subsets of amorphous semiconductors, namely tetrahedrally coordinated amorphous semiconductors and amorphous and glassy chalcogenides. Together these three volumes provide a comprehensive set of theoretical concepts and practical information needed to become conversant in the field of amorphous materials. They are suitable for advanced graduate students, postdoctoral research associates, and researchers wishing to change fields or sub-fields.The topics covered in these three volumes include (1) concepts for understanding the structures of amorphous materials, (2) techniques to characterize the structural, electronic, and optical properties of amorphous materials, (3) the roles of defects in affecting the electronic and optical properties of amorphous materials, and (4) the concepts for understanding practical devices and other applications of amorphous materials. Applications discussed in these volumes include transistors, solar cells, displays, bolometers, fibers, non-volatile memories, vidicons, photoresists, and optical disks.

Amorphous and Liquid Semiconductors

Solid state physics after solving so successfully many fundamental problems in perfect or slightly imperfect crystals, tried in recent years to attack problems associated with large disorder with the aim to understand the consequences of the lack of the long-range order. Semiconductors are much more changed by disorder than metals or insulators, and appear to be the most suitable materials for fundamental work. Considerable exploratory work on amorphous and liquid semiconductors was done by the Leningrad School since the early fifties. In recent years, much research in several countries was directed to deepen the understanding of the structural, electronic, optical, vibrational, magnetic and other proper ties of these materials and to possibly approach the present level of under standing of crystalline semiconductors. This effort was stimulated not only by purely scientific interest but also by the possibility of new applications from which memory devices in the general sense are perhaps the most challenging. The research met with serious difficulties which are absent in crystals.

Optical Properties of Solids

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.

Laser Annealing of Semiconductors

Laser Annealing of Semiconductors deals with the materials science of surfaces that have been subjected to ultrafast heating by intense laser or electron beams. This book is organized into 13 chapters that specifically tackle transient annealing of compound semiconductors. After briefly dealing with an overview of laser annealing, this book goes on discussing the concepts of solidification and crystallization pertinent to the field. These topics are followed by discussions on the main mechanisms of interaction of photon and electron beams with condensed matter; the calculation of thermophysical properties of crystalline materials; and high-speed crystal growth by laser annealing of ion-implanted silicon. The subsequent chapters describe the microstructural and topographical properties of annealed semiconductor layers and the epitaxy of ion-implanted silicon irradiated with a laser or electron beam single pulse. This text also explores the electronic and surface properties and the continuous-wave beam processing of semiconductors. The concluding chapters cover various reactions in metal-semiconductor systems, such as fast and laser-induced melting, solidification, mixing, and quenching. Laser-induced interactions in metal-semiconductor systems and the factors involved in control of the heat treatment process are also discussed in these chapters. Materials scientists and researchers and device engineers will find this book invaluable.

Laser and Electron Beam Processing of Materials

Laser and Electron Beam Processing of Materials contains the papers presented at the symposium on "Laser and Electron Beam Processing of Materials," held in Cambridge, Massachusetts, in November 1979, sponsored by the Materials Research Society. The compilation presents reports and research papers on the use of directed energy sources, such as lasers and electron beams for materials processing. The majority of the materials presented emphasize results on semiconductor materials research. Substantial findings on research on metals, alloys, and other materials are presented as well. Topics covered by the papers include the use of scanned cw sources (both photons and electrons) to recrystallize amorphous layers, enhanced substitutional solubility, solute trapping, zone refining of impurities, and constitutional supercooling. The use of lasers and electron beams to anneal ion implant damage and contacts formation, processing of ion-implanted metals, and surface alloying of films deposited on metallic surfaces are also discussed. Metallurgists, engineers, and materials scientists will find the book very insightful.

Electronic Materials

This volume constitutes the written proceedings of the Third International Conference on Materials SCience, held under the sponsorship of the Accademia Nazionale dei Lincei as the XIII summer course of the G. Donegani Foundation at Tremezzo, Italy, on September 4-15, 1972. The course of lectures was designed for scientists and engineers "d th a ,wrking knowledge of electronic materials, who sought to extend their knowledge of the newest developments in the field. The rapid pace of research and exploratory development in electronic materials has led to a preSSing need for continuing awareness and assessment of new electronic materials, as well as renewal of information in the more traditional areas. Three classes of electronic materials were selected for the course. Semiconductors provide the foundation for solid state electronics and semiconductor devices represent the most sophisti cated and advanced application of materials science and engineering known to modern technology. Yet, the march of progress in semi conductors continues ,unabated - new semiconductor materials are in the research stage, new process technology is being developed, and new devices are being conceived. The second class of materials dealt with in the course, magnetic alloys and insulators, also has a firm application base; for example, computer performance is often measured in terms of the size of the magnetic memory. The tailoring of materials to provide particular combinations of desired magnetic properties is an integral part of the development of the electronics, just as in the case of semiconductors.

Physical Processes in Laser Materials Interactions

It is a pleasure to write a few words as an introduction to the proceedings of the 1980 NATO ASI on "Physical Processes in Laser Naterial Interaction." This ASI is the ninth course of a series devoted to lasers and their applications, held under the responsibility of the Quantum Electronics Division of the European Physical Society, and for this reason known as the "Europhysics School of Quantum Electronics." Since 1971 the School has been operating with the joint direc tion of myself as representative of the academic research, and Dr. D. Roess (formerly with Siemens AEG, Munich, and now with Sick, Optik und Electronik, GmbH, Munich) for the industrial applications. Indeed the aim of the School is to alternate fundamental and applied frontier topics in the area of quantum electronics and modern optics, in order to introduce young research people from universities and industrial R&D laboratories to the new aspects of research opened by the laser.

Liquid Semiconductors

Liquid Semiconductors explores the status of the subject area's field for the purpose of being a reference to future studies and investigations. Although the main area of interest here is the electronic behavior of liquid semiconductors, the book still includes basic concepts and information, thus serving as a complete source of information in the subject area. The book is organized according to the state of development of the field. After an introductory chapter, the contents of the book are divided under three major sections. The first section (Chapters 2-4) focuses on a systematic review of experimental information and attempts to answer some of the basic questions about the field. The next section (Chapters 5-6) explores the experimental behavior, specifically the theoretical basis in its interpretation. The final section (Chapters 7-8) examines existing information regarding liquid semiconductors in terms of existing theories and concepts in order to come up with specific conclusions. This book caters to both students and scholars in the field of physics or chemistry (specifically condensed matter). Readers with a general interest in the subject area can also use the book as reference.
