Fundamental and photodetector application of van der Waals Schottky junctions

metal-semiconductor. Credit: Advanced Devices & Instrumentation The junction composed of traditional metals and 2D semiconductors is a key component of semiconductor devices. Ideally, Schottky barrier height (SBH) can be obtained based on the relative alignment of energy levels according to the Schottky-Mott rule. However, the Schottky-Mott rule was invalid due to the Fermi level pinning …
