The past four decades have witnessed many inventions and developments in the field of amorphous semiconductor such as chalcogenide glasses (Selenium, Tellurium and Sulphur ) due to its wide applications in phase change memory, switching, xerography, semiconductor devices, and optical memory devices etc. Chalcogenide glasses are covalently bonded amorphous semiconductors either binary or cross-linked form. Selenium based chalcogenide glasses exhibit phase changing properties which make them potential industrial applications in making switching devices, phase change random memory devices (PRAM) and solar cells etc. This book is framed in accordance with the syllabus of the most Indian Universities having post graduate courses in material science and nano technology such as B.Tech (Material Science and Engineering), M.Tech (Material Science and Engineering), M.Sc. (Material Science) and M.Tech (Nano Technology).
This books presents a comprehensive study on important topics pertaining amorphous semiconductor specially chalcogenide glasses materials and their characterization using different modern techniques such as X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Energy Dispersive Analysis by X-ray (EDX). Differential Scanning Calorimetry (DSC) and Thermal Gravimetric Analysis (TGA) have been explained and used in analysis of thermal characteristics of the materials in bulk powder form. Optical properties of the thin film have been observed using Ultraviolet-Visible Spectroscopy (UV-Vis) in range of 190-1100 nm.
