Abstract

We have studied superconductor/normal-metal/superconductor (SNS) junctions consisting of shea Au or Cu wires between Nh or Al banks. The Nb based junctions display inherent electron heating effects induced by the high thermal resistance of the NS boundaries. The Al based junctions show in addition subharmonic gap structures in the differential conductance dI/dV and a pronounced peak in the excess ...
