Description
Summary:Finely layered superconducting Nb/Ge composites have been fabricated with use of a novel deposition scheme and studied as model systems for quasi-two-dimensional superconductivity. Systematic variation of superconducting properties has been observed along with two- to three-dimensional crossover behavior in both the parallel critical fields below T sub(c) and the fluctuation conductivity above T sub(c).
