Gneralized McMillan tunneling model of the superconducting proximity effect. Specific heat jump

Abstract

The reduced specific heat jumps for the superconducting (S) side and the normal (N) side of a strongly coupled N-S composite have been calculated by using the generalized McMillan tunneling model of the superconducting proximity effect. Both cases AN = 0 and AN # 0 (where AN is the BCS interaction constant) have been stud&d. The results obtained by using the generalized model are significantly different from the ones given by the McMillan tunneling model.
