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.
Although amorphous semiconductors have been studied for over four decades, many of their properties are not fully understood. This book discusses not only the most common spectroscopic techniques but also describes their advantages and disadvantages. - Provides information on the most used spectroscopic techniques - Discusses the advantages and disadvantages of each technique
This book highlights the achievements of the self-taught inventor, scientist, manufacturer and entrepreneur, Stanford R Ovshinsky. This remarkable individual could, without special training, compete with the well-funded establishments of learning and industry in the second half of the last century and leave us an incredible legacy of brilliant innovations with a lasting impact on our lives. His achievements extend over amazingly diverse fields and have or are prone to create new industries of great societal value.The phase change memories of commonly used rewritable CDs and DVDs as well as of new flash memories are his invention; so are the Ni Metal hydride batteries which are the enabling batteries for electric and hybrid/electric vehicles. The future hydrogen economy will utilize his efficient and safe hydrogen storage alloys. He has developed light and ultralight photovoltaic solar panels for converting sunlight into electricity and built the largest manufacturing facility for thin film flexible solar roofing materials. A common theme of his inventions is the synthesis of new materials utilizing novel aspects of structural and compositional disorder.The book explains for each of Ovshinsky''s innovations the essence of his pioneering ideas and inventions. These introductions are followed by a selection of Ovshinsky''s seminal publications and, for each subject category, a list of his patents which reveal the inventive mind of this unusually creative person. Ovshinsky''s example of gaining a deep understanding of the science underlying his inventions, his perseverance as well as his ability to attract and inspire talented collaborators will be a role model for entrepreneurs of this century.
Amorphous semiconductors are subtances in the amorphous solid state that have the properties of a semiconductor and which are either covalent or tetrahedrally bonded amorphous semiconductors or chelcogenide glasses.
