Metal semiconductor contacts In the lecture, we have learnt the Schottky junction and Ohmic contact formed by n-type semiconductor and the metal. What will happen if the semiconductor is a p-type semiconductor? Draw the band diagram for the p-type Schottky junction. Describe the process of formation. State clearly I the position of the Fermi levels of the semiconductor and the metal; II The flow of charge carriers to achieve equilibrium; III band bending direction; IV depletion region (if any).
