Classification of typical semiconductor films
WebThin film semiconductors. A survey is made of the field of electronic carrier transport in semiconductor films with special reference to active thin film devices and their typical behaviour. Films below 1000 å are called thin, films above 10,000 å (1μ) are called thick. WebThis technology is known as thin-film technology. Thin films are deposited over a wide range of substrates (2–4). Thin films can be classified based on material into various categories: for example metallic, dielectric, organic or semiconductor films. The material can be in monocrystalline, polycrystalline or amorphous forms.
