Abstract
We report on the first observation of the re-entrance of the metallic resistance in a mesoscopic proximity superconductor. This occurs at lo w temperature when the coherence length of electron pairs with a therm al energy is larger than the sample size. This regime breaks down when the voltage is increased above the Thouless energy. We find a qualita tive agreement between experimental results and the quasiclassical the ory including the Usadel equations.
