Please, help explain the following concept: We know that semiconductor bandgap changes with temperature. We also know qualitatively how the doping energy level (E_D for donors and E_A for acceptors) changes with increasingdoping density. Give a qualitative description of what happens to donor energy level (E_D) as N_D increases. Whathappens to the Fermi level, E_F at very high doping density? Make comment on the Boltzmannapproximation as the doping density increases to very high concentrations. Please illustrate the aboveusing schematics (Band Diagram).

Please, help explain the following concept: We know that semiconductor bandgap changes with temperature. We also know qualitatively how the doping energy level (E_D for donors and E_A for acceptors) changes with increasing
doping density. Give a qualitative description of what happens to donor energy level (E_D) as N_D increases. What
happens to the Fermi level, E_F at very high doping density? Make comment on the Boltzmann
approximation as the doping density increases to very high concentrations. Please illustrate the above
using schematics (Band Diagram).
