Calculate the Burstein shift in the absorption edge of a direct semiconductor with parabolic bands due to heavy doping (p-type, say), at such a low temperature that the holes are degenerate. Neglect excitons. Note that the shift is not simply the Fermi energy of the holes and involves the mass of both conduction and valence bands. What should happen to the shape of the absorption edge?
