Abstract

We have measured the differential resistance of mesoscopic gold wires of different lengths connected to an aluminum superconductor as a function of temperature and voltage. Our experimental results differ substantially from theoretical predictions which assume an infinite temperature-independent gap in the superconductor. In addition to taking into account the temperature dependence of the gap, we must also introduce a temperature-dependent inelastic scattering length in order to fit our data.
