Devices based on disordered semiconductors have wide applications. It is difficult to imagine modern life without printers and copiers, LCD monitors and TVs, optical disks, economical solar cells, and many other devices based on disordered semiconductors. However, nowadays books that discuss disordered (amorphous, nanocrystalline, microcrystalline) semiconductors focus, as a rule, on either physics of materials or physics of devices that are based on these materials. This book connects characteristic features of the atomic and electronic structures of disordered semiconductors and the device design process on the basis of these materials. Compared with the first edition, this book takes into account the latest developments of disordered semiconductors and devices. It has new sections on the structures of carbon-based amorphous and nanocomposite films and atomic and electronic structures of organic semiconductors.

This 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.

To identify the specific features of the kinetics of oxidation of polymer mixtures, determine the key structural elements, and create a model that can describe the mechanism of thermal oxidation of polymer mixtures, it is necessary to determine the relation between the initial structure of a polymer mixture, structural rearrangements associated with oxidation and the kinetics of the process. The aim of this book is to elucidate the complicated problem concerning the connection between the structure and mechanism of oxidation of heterogeneous and heterophase polymer systems. The material presented in this book concerns the specific features of the kinetics of oxidation and those of the structure of polymer systems. The book deals with an analysis of the key factors that can affect principally the mechanism of thermal oxidation of polymer mixtures, determines the role of the phase morphology, structure of components, and the interface layer (or boundary) in the kinetics of oxidation of heterophase system by an example of mixtures of polyolefines. Along with the kinetics of oxidation of heterophase systems, problems of investigation of their structural parameters in the oxidized state are considered. With this aim, the material presented in the book concerns not only the mechanism of oxidation of polymer mixtures but also homopolymers of diverse morphology and model systems.
