Amorphous materials differ significantly from their crystalline counterparts in several ways that create unique issues in their use. This book explores these issues and their implications, and provides a full treatment of both experimental and theoretical studies in the field.Advances in Amorphous Semiconductors covers a wide range of studies on hydrogenated amorphous silicon, amorphous chalcogenides, and some oxide glasses. It reviews structural properties, properties associated with the charge carrier-phonon interaction, defects, electronic transport, photoconductivity, and some applications of amorphous semiconductors. The book explains a number of recent advances in semiconductor research, including some of the editors' own findings. It addresses some of the problems associated with the validity of the effective mass approximation, whether K is a good quantum number, and the concepts of phonons and excitons. It also discusses recent progress made in understanding light-induced degradations in amorphous semiconductors, which is seen as the most limiting problem in device applications.The book presents a comprehensive review of both experimental and theoretical studies on amorphous semiconductors, which will be useful to students, researchers, and instructors in the field of amorphous solids.

Metal Organic Frameworks: Fundamentals to Advanced offers a substantial and complete treatment of published results. The book includes a summary of current research, along with an in- depth explanation of Metal organic frameworks (MOFs) and applications in this versatile area. Metal organic frameworks (MOFs) are structured frameworks made up of metal ions and organic molecules. These materials are similar to sponges and can absorb, retain and remove molecules from their pores. As a result, metal-organic frameworks (MOFs) are the most rapidly evolving substances in chemistry with the highest surface areas due to their well-ordered pore structure.The exciting and vast surface area allows for more chemical reactions and molecule adsorption, hence this new resource provides the newest updates on the topics covered.Covers the synthetic advantages and versatile applications of metal-organic frameworks (MOFs) due to their organic-inorganic hybrid nature and unique porous structureIncludes energy applications such as batteries, fuel storage, fuel cells, hydrogen evaluation reactions and super capacitorsFeatures information on using MOFs as a replacement to conventional engineering materials as they are lightweight, less costly, environmentally-friendly and sustainable

Thus far the top-performing thermoelectric materials have included toxic elements or materials that are not abundant or expensive and difficult to produce. Consequently metal oxide materials are now being investigated as potential thermoelectric materials. Metal Oxide-Based Thermoelectric Materials reviews the characteristics of metal oxide materials in comparison to other materials utilized for thermoelectric applications. In particular, there is discussion of the intrinsic advantages of metal oxide materials such as their chemical and thermal stability, environmental friendliness, cheap raw material costs, and chemical flexibility. In addition, the book includes information on their high-temperature stability, adjustable electronic and phonon transport behavior, and well-established simple production processes. Strategies to enhance the thermoelectric properties of metal oxide materials are emphasized in the book. Finally, emerging applications of metal oxide-based thermoelectrics are touched on with an overview of the remaining challenges and opportunities towards commercial translation. Metal oxide-based thermoelectric materials is a suitable reference book for researchers and scientists in academia and R&D in the subject areas of materials science and engineering and energy.
