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.
Although some pure elements and many compounds display semiconductor properties, silicon, germanium, and compounds of gallium are the most widely used in electronic devices. Elements near the so-called metalloid staircase, where the metalloids are located on the periodic table, are usually used as semiconductors.he semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p-and n-type dopants. A single semiconductor crystal can have many p-and n-type regions; the pân junctions between these regions are responsible for the useful electronic behaviour.
