WebJun 1, 2012 · Graphene is a zero-gap semiconductor whose Fermi energy can be adjusted by electrostatic gating owing to its two-dimensional (2D) nature (3–5).Because graphene is metallic at a sufficiently large Fermi energy, a Schottky barrier (SB) forms at the interface between the doped graphene and the semiconductor (6–10).However, SB between … 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 …
