Inconsistency between E_fermi and carrier concentrations

Dear Alex,

How should concentration and E_fermi in the DOS section of AMSET be correlated?

  1. Is it simply a Kohn-sam eigenvalue?
  2. Or is it aligned to VBM or Intrinsic DOS Fermi level?

If you look at the picture below, you are a little puzzled because the E_fermi of -1E-2 concentration and +1E-2 concentration are the same.

Is it not possible to calculate AMSET for the low concentration? If not, at least how much? I wonder.
