A Schottky barrier, named after Walter H. Schottky, is a potential energy barrier for electrons formed at a metal–semiconductor junction. Schottky barriers have rectifying characteristics, suitable for use as a diode. One of the primary characteristics of a Schottky barrier is the Schottky barrier height, … Meer weergeven When a metal is put in direct contact with a semiconductor, a so called Schottky barrier can be formed, leading to a rectifying behavior of the electrical contact. This happens both when the semiconductor is At the basis of the description of the Schottky barrier formation through the band diagram formalism, there are three main assumptions: 1. The … Meer weergeven • Ohmic contact • Schottky diode • Diode • Metal-induced gap states Meer weergeven In a rectifying Schottky barrier, the barrier is high enough that there is a depletion region in the semiconductor, near the interface. This gives the barrier a high resistance when small voltage biases are applied to it. Under large voltage bias, the electric current flowing … Meer weergeven A Schottky diode is a single metal–semiconductor junction, used for its rectifying properties.
