Title: Coherent diffusive transport mediated by Andreev reflections at V={Delta}/e in a mesoscopic superconductor/semiconductor/superconductor junction

Abstract

We present experiments revealing a singularity in the coherent current across a superconductor/semiconductor/superconductor (SSmS) junction at the bias voltage corresponding to the superconducting energy gap V={Delta}/e. The SSmS structure consists of highly doped GaAs with superconducting electrodes of aluminum configured as an interferometer. The phase-coherent component of the current is probed as the amplitude of h/2e vs magnetic-field oscillations in the differential resistance of the interferometer. {copyright} {ital 1997} {ital The American Physical Society}
