Abstract
Tin‐tinoxide‐tin Josephson junctions have been fabricated by glow discharge oxidation of films evaporated in the 10−7−10−8‐Torr range. Saturation of the maximum zero‐voltage current with increasing junction length has been observed for a crossed film geometry, and a linear increase of maximum zero‐voltage current with junction length has been observed for an overlap geometry. Approximate agreement with the theory of Owen and Scalapino has been obtained.Keywords
