Metal–semiconductor junction

As metal -semiconductor contact, contact between metals and semiconductors is known in semiconductor physics and technology in general. Metal - semiconductor junctions are present in the contacting of semiconducting materials, and thus are one of the most important elements in semiconductor devices and microelectronic circuitry; they may also constitute separate devices, however, for example Schottky diode.

These transitions occur generally in two forms, firstly as polungsunabhängige contacts with a linear current -voltage characteristic, so-called ohmic contact, on the other hand greatly polungsabhängige contact with the current-voltage characteristic of a diode, the so-called Schottky contacts. Form, which is formed at the junction of a metal and a semiconductor, depends primarily on the position of Fermi level in the metal and the semiconductor on, and is thus also dependent on the doping of the semiconductor. Detailed descriptions of this can be found in the articles of two contact forms.
