摘要
Using the new Green's function calculation of Arnold and an appropriate modification of the McMillan-Rowell procedure, it is demonstrated that tunneling characteristics of suitable proximity junctions may be inverted to determine the properties of superconductors which do not oxidize satisfactorily. The junctions employed are of the form M-Al2O3-Al/S (where S is the superconductor of interest). The Al thickness is less than 100 Å and the Al/S interface is specularly transmitting. Quantitative values for ΔS(E) and ΔN(E) are obtained for S=Nb, N=Al. © 1979.
