Consider a silicon crystal whose band gap energy is Eg=1.124eVE_g = 1.124 eVEg​=1.124eV and is kept at T=300KT = 300 KT=300K.

If the Fermi level, EFE_FEF​, is located at precisely the middle of the band gap, what is the probability of finding an electron (or equivalently the probability of a state being occupied) at E=EC+kBTE = E_C + k_BTE=EC​+kB​T?

Doping changes the Fermi energy of a semiconductor. Consider silicon, with a gap of 1.11 eV between the top of the valence band and the bottom of the conduction band. At 300 K the Fermi level of the pure material is nearly at the midpoint of the gap. Suppose that silicon is doped with donor atoms, each of which has a state 0.13 eV below the bottom of the silicon conduction band, and suppose further that doping raises the Fermi...
