Abstract
Electrical-transport properties of mesoscopic junctions consisting of a ballistic two-dimensional electron gas coupled at two sides to overl aying superconducting contacts are presented, The properties suggest t hat, despite the presence of transport limiting barriers in the sample , supercurrents are carried by a few modes that have near-unity transm ission probability. We can qualitatively account for the presence of t hese resonances by the theory of disorder-induced opening of tunnel ch annels.
