Question

Consider an intrinsic semiconductor with the following simple density of states: The density of states is equal to a constant, Dv, in the valence band, and equal to another constant, Dc, in the conduction band. (Something like this occurs in amorphous semiconductors.) Assume that Eg = Ec - Ev, is much greater than kBT. (a) Solve for n, the density of electrons in the conduction band, and for p, the density of holes in the valence band, in terms of , the chemical potential. (b) Solve for the product np in terms of Eg. (c) Solve for , the chemical potential in terms of Eg, T, Dv, and Dc.
