摘要：
NbNbOx–PbIn junctions are investigated, especially in view of aging. The penetration depths λ(0) of the niobium films are equal for critical temperatures between 8.1 and 8.6 K. The properties of the niobium films do not change with time. The penetration depth, the critical temperature, and the residual resistance ratio of the PbIn films produced by first evaporation of lead and after that of indium change with time. The tunneling resistance of the NbNbOx–PbIn junctions decreases by a factor of 3 to 4 in the course of more than two years. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
