what is a semiconductor device
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 pân 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.
