For information on semiconductor physics, see semiconductor. Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide, as well as organic semiconductors.Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications. semiconductor diode is a device typically made from a single pân junction. At the junction of a p-type and an n-type semiconductor there forms a depletion region where current conduction is inhibited by the lack of mobile charge carriers.
Semiconductor materials are nominally small band gap insulators. The defining property of a semiconductor material is that it can be doped with impurities that alter its electronic properties in a controllable way. Because of their application in the computer and photovoltaic industryâin devices such as transistors, lasers, and solar cellsâthe search for new semiconductor materials and the improvement of existing materials is an important field of study in materials science.
