WebSchottky barrier is a depletion layer formed at the junction of a metal and n-type semiconductor. In simple words, schottky barrier is the potential energy barrier formed at the metal-semiconductor junction. The electrons have to overcome this potential energy barrier to flow across the diode. Web1. n-type semiconductor: Pentavalent impurities (Ex: As, P) are added which introduces an extra valence electron which requires lesser energy for conduction. Addition of pentavalent impurity adds a new energy level (called donor levels) near the conduction band in the energy band diagram. 2. p-type semiconductor: Trivalent impurities (Ex: B, In ...
