Chemical potential of a semiconductor

(a) What is the chemical potential of a semiconductor?

(b) Describe how doping changes the chemical potential of a semiconductor. State where the chemical potential is relative to the top of the valence band and bottom of the conduction band for intrinsic, n-doped, and p-doped semiconductors.

(c) How is the chemical potential related to the concentration of electrons in the conduction band?
