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 viewpointDeals with, amongst others, preparation techniques, structural, optical and electronic properties, and light induced phenomenaExplores different types of amorphous semiconductors including amorphous silicon, amorphous semiconducting oxides and chalcogenide glassesApplications include solar cells, thin film transistors, sensors, optical memory devices and flat screen devices including televisions
