We consider the chemical potential for the case of an intrinsic semi-conductor. Which of the following statements is correct? More than one answer might be correct. (Hint: examine the equation describing the chemical potential; )

A. The chemical potential will move closer to the valence band if the effective mass of the electron is larger than that of the hole at finite temperature.
B. The chemical potential is not in the gap centre if the temperature is zero.
C. The chemical potential is the same for these two conditions: 1) the effective electron mass=hole mass and 2) the temperature is absolute zero.
D. The chemical potential is closer to the valence band if the hole effective mass equals the electron effective mass.
E. The effective masses of the electrons and holes do not affect the chemical potential
F. The chemical potential is zero at T=0K.
G. The chemical potential will move closer to the conduction band if the effective mass of the electron is larger than that of the hole at finite temperature.

In this exercise, we will investigate the chemical potential μμ upon a change in volume. We will use the fact that F=U−TSF=U−TS and μ=∂F/∂N. We will compute μ(Vf)−μ(Vi)μ(Vf)−μ(Vi) In all questions, take N=20 moles (which is 20 times Avagodro's number of particles), T=300 K, Vi=0.01 m3,Vf=0.02 m3 1) For a gas with an excluded volume: U=3/2NkT+const S=Nkln(V−bN)+const If bb=10-28 m3, compute μ(Vf)−μ(Vi) 2.) For a gas with an excluded volume and attraction between the particles: U=3/2NkT−aN^2/V+const S=Nkln(V−bN)+const If aa=10-49 m3...

Consider a case in which we have an Einstein solid that is neither at high or low temperature. In this case, we cannot use either the N>>q or q>>N approximation. In this case both N and q are >> 1. Derive an expression for the chemical potential then discuss how this more general result differs from and/or could correlate to the low and high temperature cases. Thermodynamics

Consider a new market in which we have five potential sellers. Seller A has costs of $20, Seller B has costs of $41, Seller C has costs of $19, Seller D has costs of $25, and Seller E has costs of $31. If the good produced has a market price of $30, total producer surplus in the market will equal $________.(Carefully follow all numeric directions.)
