Book Description
Noncrystalline (NC) solids, as is well known, lack the long range order of crystals. Accordingly, they exhibit scattering, e.g., x-ray, electron, and neutron, but not the diffraction patterns characteristic of crystals. The intensity distributions from NC solids are usually transformed into radial distribution functions (RDF), but the interpretation of the RDF's is not unique. The lack of long-range order, and the non-uniqueness of the structural interpretation, have constituted the main obstacles to the usual solid state physics approach which has been so successful in dealing with crystals. As a corrolary, questions of local order and structure have frequently been de-emphasized. This monograph contains a collection of chapters many of which emphasize local-structure and chemical bonding as opposed to long-range order. Most of the chapters were chosen from talks given at the international symposium, "Structure and Bonding in Noncrystalline Solids," held in Reston, Virginia in May of 1983. Other chapters, however, were simply submitted independently of the Reston conference. Thus, this book is not a proceedings of that conference, nor was it ever intended to be. The chapters presented here range from theory of bonding and structure, to structurally oriented measurements of various kinds, e.g., ESR, Raman, to more applied chapters. Our goal was to produce a monograph that enhances understanding of the structures of NC solids.

Book Description
One of the motivating questions in materials research today is, how can elements be combined to produce a solid with specified properties? This book is intended to acquaint the reader with established principles of crystallography and cohesive forces that are needed to address the fundamental relationship between the composition, structure and bonding. Starting with an introduction to periodic trends, the book discusses crystal structures and the various primary and secondary bonding types, and finishes by describing a number of models for predicting phase stability and structure. Containing a large number of worked examples, exercises, and detailed descriptions of numerous crystal structures, this book is primarily intended as an advanced undergraduate or graduate level textbook for students of materials science. It will also be useful to scientists and engineers who work with solid materials.

Book Description
Chalcogenide glass is made up of many elements from the Chalcogenide group. The glass is transparent to infrared light and is useful as a semiconductor in many electronic devices. For example, chalcogenide glass fibers are a component of devices used to perform laser surgery. This book is a comprehensive survey of the current state of science and technology in the field of chalcogenide semiconductor glasses. While the majority of the book deals with properties of chalcogenide glass, chapters also deal with industrial applications, synthesis and purification of chalcogenide glass, and glass structural modification. The first individual or collective monograph written by Eastern European scientists known to Western readers regarding structural and chemical changes in chalcogenide vitreous semiconductors(CVS)Chapters written by B.G. Kolomiets who discovered the properties of chalcogenide glass in 1955Provides evidence and discussion for problems discussed by authors from opposing positions.

Book Description
This volume and its two companion volumes, entitled Tetrahedrally-Bonded Amorphous Semiconductors and Localization and Metal-Insulator Transitions, are our way of paying special tribute to Sir Nevill Mott and to express our heartfelt wishes to him on the occasion of his eightieth birthday. Sir Nevill has set the highest standards as a physicist, teacher, and scientific leader. Our feelings for him include not only the respect and admiration due a great scientist, but also a deep affection for a great human being, who possesses a rare combination of outstanding personal qualities. We thank him for enriching our lives, and we shall forever carry cherished memories of this noble man. Scientists best express their thanks by contributing their thoughts and observations to a Festschrift. This one honoring Sir Nevill fills three volumes, with literally hundreds of authors meeting a strict deadline. The fact that contributions poured in from all parts of the world attests to the international cohesion of our scientific community. It is a tribute to Sir Nevill's stand for peace and understanding, transcending national borders. The editors wish to express their gratitude to Ghazaleh Koefod for her diligence and expertise in deciphering and typing many of the papers, as well as helping in numerous other ways. The blame for the errors that remain belongs to the editors.

Book Description
This book provides introductory, comprehensive, and concise descriptions of amorphous chalcogenide semiconductors and related materials. It includes comparative portraits of the chalcogenide and related materials including amorphous hydrogenated Si, oxide and halide glasses, and organic polymers. It also describes effects of non-equilibrium disorder, in comparison with those in crystalline semiconductors.
