Graphene schottky contact
WebMar 26, 2024 · The graphene/graphene-like germanium carbide interface forms a p-type Schottky contact. The p-type Schottky barrier height decreases as the interlayer distance decreases and finally the contact transforms into a p-type Ohmic contact, suggesting that the Schottky barrier can be effectively tuned by changing the interlayer distance in the … WebA 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 Φ B (see figure). The value of Φ B …
