Description
Book SynopsisThis textbook links characteristic features of atomic and electronic structures of disordered semiconductors to the device design process. It begins with a description of general concepts of disordered semiconductors, their atomic structures, the structure of energy bands, and their defects, as well as their electrical, optical, and photovoltaic properties. Since weak sensitivity to impurities is a distinguishing feature of disordered semiconductors, methods of property control and thin-film preparation methods are the areas of focus. Finally, applications of disordered semiconductors in various devices are considered.
Trade Review"Readers of this book are taken on a logical journey beginning with three comprehensive chapters on the fundamental properties of disordered semiconductors, followed by two outlining the methods used to control the properties and fabricate thin films of these materials, and concluding with two chapters describing the current status of their applications. Students and scientists entering or working in the field will find it an exceedingly valuable and useful text."

"This book provides under a single cover and from a single perspective a description of physics and applications of disordered semiconductors. With complex issues explained using a simple language this book will be very valuable source of information for graduate and postgraduate students in the field of semiconductor physics and devices."
—Dr Alex Kolobov, Advanced Industrial Science and Technology, Japan
"This book comprehends a wide group of questions: atomic and electron structure, electrical, optical, photoelectric properties and application of disordered semiconductors, first of all the hydrogenated amorphous silicon, its alloys and chalcogenide glassy semiconductors. Important peculiarity of the book is the consideration of the main technologies of both thin films and devices fabrication. The book is interesting to all workers in the field."
—Prof. Victor Lyubin, Ben-Gurion University, Israel
