Consider an intrinsic semiconductor with the following simple density of states: The density of states De) is equal to a constant, Dy, in the valence band, and equal to another constant, De, in the conduction band. (Something like this occurs in amor- phous semiconductors.) Assume that E, = EC - E, is much greater than kgT. (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 p, the chemical potential. (b) Solve for the product np in terms of Eg. (c) Solve for fi, the chemical potential in terms of Eg, T, D, and De
