SUPERCURRENT IN A MESOSCOPIC PROXIMITY WIRE

Recent experiments on the proximity induced supercurrent in mesoscopic normal wires revealed a surprising temperature dependence. They sugge st clean-limit behavior although the wires are strongly disordered. We demonstrate that this unexpected scaling is actually contained in the conventional description of diffusive superconductors and find excell ent agreement with the experimental results. In addition toe propose a SQUID-like proximity structure for further experimental investigation s of the effects in question.
