Schottky junction and Ohmic contact

Read Streetman text and/or references about the Schottky junction and Ohmic contact between
metal and semiconductor. Address the following topics.

1. Briefly describe a Schottky junction. Provide an example of metal-semiconductor contact
   that forms a Schottky junction (name the metal and semiconductor).
2. Draw the energy band diagrams of a Schottky junction under equilibrium, forward bias, and
   reverse bias.
3. Describe the I-V characteristics of a Schottky junction under forward and reverse bias.
4. Briefly describe Ohmic contact. Provide an example of metal-semiconductor Ohmic contact
   (name the metal and semiconductor) and draw the energy band diagram.
