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. * Developed from both a theoretical and experimental viewpoint * Deals with, amongst others, preparation techniques, structural, optical and electronic properties, and light induced phenomena * Explores different types of amorphous semiconductors including amorphous silicon, amorphous semiconducting oxides and chalcogenide glasses * Applications include solar cells, thin film transistors, sensors, optical memory devices and flat screen devices including televisions
