Schottky barrier height is the energy threshold that electrons must overcome to cross the interface between a metal and a semiconductor. It dictates whether the junction behaves as an ohmic contact with low resistance or a rectifying diode. Device physicists engineer this barrier by selecting specific metals and doping concentrations to tune the forward voltage drop and leakage current.

We need to lower the SBH on the source contacts to improve the drive current of the transistor.
