Germanium has a band gap of 0.67 eV. Doping with arsenic adds donor levels in the gap 0.01 eVeV 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.  How far below the bottom of the conduction band is the Fermi level in this case?  Express your answer in eV.
