3. A metal contact to a n-type semiconductor can be considered as a p*-n junction with NA > ND. Draw an energy band diagram of the contact showing the Schottky barrier eoz and the depletion width d. Then draw the energy band diagram in forward and reverse biased conditions. Indicate how the +V or -V bias affects the contact potential and the depletion width. Explain how the bias changes the forward current due to the injection of electrons from the semiconductor into the metal, and the reverse current Io from the flow of metal free carriers into the semiconductor. Show that the rectifying behavior is just like that in a p-n junction.
