Abstract

The effect of the dimensional crossover on localization/interaction and superconductivity in ultrathin Si/Nb multilayers has been studied by systematically varying the Nb and Si layer thicknesses to separately control the degree of disorder and the anisotropy. A small coupling is sufficient to drive the strongly localized states into the weak localization regime. As a result, superconductivity may persist up to an R much larger than h (2e)2. The results are in qualitative agreement with a recently proposed anisotropic tight-binding model for localization.
