Singular Current Density in the Planar Superconductor/Normal Metal/Superconductor Junction
Published
Author(s)
Abstract
Interfacial resistivity (p) is crucial in limiting the maximum current density (Jnmax) in certain superconductor/metal junctions: as p decreases, Jnmax keeps rising until ultimately limited by the superconductor's critical current density. This little known effect is theoretically studied in a circuit with junctions formed by two superconducting contacts on the same face of a normal metal rectangular bar. The corresponding singularly perturbed mixed boundary value problem is solved numerically, and Jnmax is computed over a wide range of p and {l}, the gap between the contacts. Scaling behavior is found, and used to obtain an approximate formula for Jnmax (p,{l}).Citation
