    Metal-Semiconductor Junctions

    The contact of metal and semiconductor can lead to the formation of a junction with either Schottky or Ohmic behavior.
    Schottky Barriers
    Schottky barriers arise when a metal with a work function (Φm) contacts a semiconductor with a different work function (Φs). Initially, electrons transfer until the Fermi levels of the metal and semiconductor align at equilibrium. For instance, if Φm > Φs, the semiconductor Fermi level is higher than the metal's before contact. The...
