Question

Recall the condition of strong inversion in terms of the surface potential, psis = 2psiB. Is this condition valid for the case where the quantization effect due to confinement in the surface normal direction is significant in the surface inversion layer? Justify/explain your answer. If it is not valid, then how should the surface potential value be changed, approximately, for a strong inversion ? Assume that the ground state energy due to quantization is at E0 = qpsio above the conduction band edge Ec.
