Semiconductor device The semiconductor material used in devices is doped under highly controlled conditions in a fabrication facility, or fab, to control precisely the location and concentration of p-and n-type dopants. The junctions which form where n-type and p-type semiconductors join together are called p–n junctions. semiconductor diode is a device typically made from a single p–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.

What are Semiconductors used for? In a crystalline pattern i.e. crystal lattice, semiconductors have very electrons because their atoms are closely grouped together. In a semiconductor, current can be carried out by the flow of electrons or by the flow of positively charged holes in the electron structure of the material. Depending on this semiconductors are classified into two categories: Intrinsic Semiconductor.

semiconductor sem·i·con·duc·tor. n. 1. Any of various solid crystalline substances, such as germanium or silicon, having electrical conductivity greater than insulators but less than good conductors, and used especially as a base material for computer chips and other electronic devices. 2.ny of various solid substances, such as silicon or germanium, that conduct electricity more easily than insulators but less easily than conductors. Semiconductors are able to do this because they have a small number of electrons that have escaped from the bonds between the atoms, leaving open spaces.
