Potential barrier in semiconductor
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, denoted by ΦB (see figure). The value of ΦB depends on the combination of metal and se… Web12 Jul 2016 · The barrier potential is balanced by the metal to semiconductor contact potentials in the circuit.To show the reading a small amount of current must flow through …
