W. Lee, MCMILLAN-ROWELL RESONANCE IN THE STRONG-COUPLING NS TUNNELING JUNCTIONS WITH REFLECTING BOUNDARY, Journal of superconductivity, 7(3), 1994, pp. 613-616
A proximity junction with strong-coupling N, S and a reflecting NS bou
ndary is considered. Using the formula derived in the framework of the
Eliashberg and quasiclassical theories in the step approximation, the
tunneling density of states is calculated for a model system, and the
effects of the reflecting boundary and the phonons in the N, as well
as S, layers on the McMillan-Rowell oscillation in the tunneling densi
ty of states are discussed.
