SOLVED:Germanium has a band gap of 0.67 eV. Doping with arsenic adds donor levels in the gap 0.01 eV below the bottom of the conduction band. At a temperature of 300 K , the probability is 4.4 ×10^-4 that an electron state is occupied at the bottom of the conduction band. Where is the Fermi level relative to the conduction band in this case?

Pure germanium has a band gap of 0.67 eV. The Fermi energy is in the middle of the gap. (a) For temperatures of 250  K, 300  K, and 350  K, calculate the probability f(E) that a state at the bottom of the conduction band is occupied. (b) For each temperature in part (a), calculate the probability that a state at the top of the valence band is empty. | Numerade
