Properties and Applications of Amorphous Materials


Book Description

The aim of this NATO ASI has been to present an up-to-date overview of current areas of interest in amorphous materials, with particular emphasis on electronic properties and device applications. In order to limit the material to a manageable amount, the meeting was concerned almost exclusively with semiconducting materials. This volume should be regarded as a follow-on to the NATO ASI held in Sozopol, Bulgaria in 1996 and published as "Amorphous Insulators and Semiconductors" edited by M.F. Thorpe and M.1. Mitkova (Kluwer Academic Publishers, NATO ASI series, 3 High Technology - Vol. 23). The lectures and seminars fill the gap between graduate courses and research seminars. The lecturers and seminar speakers were chosen as experts in their respective areas, and the lectures and seminars that were given are presented in this volume. During the first week of the meeting, an emphasis was placed on introductory lectures while the second week focused more on research seminars. There were two very good poster sessions that generated a lot of discussion, but these are not reproduced in this volume as the editors wanted to have only larger contributions to make the proceedings more coherent.




Crystalline and Non-crystalline Solids


Book Description

The structural properties of materials play a fundamental role in the determination of their suitability for a specific application. This book is intended as a contribution to the efforts to increase the knowledge of the influence exerted on the properties of materials by their crystalline or amorphous structure. To this aim, some of the materials that are most promising for their use in different technological fields have been studied, namely graphene, titanium oxide, several types of functional metal oxides, porphyrinic crystalline solids, plasma deposited polymers, amorphous silicon, as well as hydrogenated amorphous carbon. These materials have been presented by the authors for their use in different applications, including microelectronics, photonics, and biomedicine.




Structure and Bonding in Crystalline Materials


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.




Conduction in Non-Crystalline Materials


Book Description

This second edition deals in an elementary way with electrons in non-crystalline systems. It reflects advances in the theory of interactions in non-crystalline systems, provides a more detailed discussion of the "minimum metallic conductivity", and addresses the relevance of disorder in the new high-temperature semiconductors.




Physical Properties of Amorphous Materials


Book Description

The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on "Fundamentals of Amorphous Materials and Devices" was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.




Development History Of Ancient Chinese Glass Technology


Book Description

Worldwide research on ancient glass began in the early 20th century. A consensus has been reached in the community of Archaeology that the first manmade or synthetic glasses, based on archaeological findings, originated in the Middle East during the 5000-3000's BC. By contrast, the manufacturing technology of pottery and ceramics were well developed in ancient China. The earliest pottery and ceramics dates back to the Shang Dynasty - the Zhou Dynasty (1700 BC-770 BC), while the earliest ancient glass artifacts unearthed in China dates back to the Western Han Dynasty. Utilizing the state-of-the art analytical and spectroscopic methods, the recent findings demonstrate that China had already developed its own glassmaking technology at latest since 200 BC. There are two schools of viewpoint on the origin of ancient Chinese glass. The more common one believes that ancient Chinese glass originated from the import of glassmaking technology from the West as a result of Sino-West trade exchanges in the Western Han Dynasty (206 BC-25 AD). The other scientifically demonstrates that homemade ancient Chinese glass with unique domestic formula containing both PbO and BaO were made as early as in the Pre-Qin Period or even the Warring States Period (770 BC-221 BC), known as Yousha or Faience.This English version of the previously published Chinese book entitled Development History of Ancient Chinese Glass Technology is for universities and research institutes where various research and educational activities of ancient glass and history are conducted. With 18 chapters, the scope of this book covers very detailed information on scientifically based findings of ancient Chinese glass development and imports and influence of foreign glass products as well as influence of the foreign glass manufacturing processes through the trade exchanges along the Silk Road(s).




Electronic Processes in Non-Crystalline Materials


Book Description

A reissue of a classic Oxford text. The book sets out theoretical concepts and makes comparisons with experiments for a wide variety of phenomena in non-crystalline materials.




Amorphous and Nanocrystalline Materials


Book Description

Amorphous and nanocrystalline materials are a class of their own. Their properties are quite different to those of the corresponding crystalline materials. This book gives systematic insight into their physical properties, structure, behaviour, and design for special advanced applications.




Structure of Materials


Book Description

This highly readable, popular textbook for upper undergraduates and graduates comprehensively covers the fundamentals of crystallography and symmetry, applying these concepts to a large range of materials. New to this edition are more streamlined coverage of crystallography, additional coverage of magnetic point group symmetry and updated material on extraterrestrial minerals and rocks. New exercises at the end of chapters, plus over 500 additional exercises available online, allow students to check their understanding of key concepts and put into practice what they have learnt. Over 400 illustrations within the text help students visualise crystal structures and more abstract mathematical objects, supporting more difficult topics like point group symmetries. Historical and biographical sections add colour and interest by giving an insight into those who have contributed significantly to the field. Supplementary online material includes password-protected solutions, over 100 crystal structure data files, and Powerpoints of figures from the book.
