Question

Problem #2: A piece of Si doped ND=1x1017 cm -3 has a uniform excess electron and hole concentrations of 1x1016cm -3 excited and maintained in the material.

A) Calculate the equilibrium electron and hole concentrations and the position of EF.

B) Calculate the total electron and hole concentrations, the positions of FN and FP, as well as the quasi Fermi level separation (FN-FP)

C) Draw a band diagram including EC, EV, Ei, EF, FN, and FP.
