Abstract
Superconductor/normal-metal (SN) interfaces of high transparency exhibit remarkably different properties for electric charge and energy transfer, respectively. Quasiparticles with energy e below the energy gap D of the superconductor cannot enter the superconductor. This implies a high thermal resistance of the SN boundary since energy is exclusively carried by the quasiparticles. 1 In contrast, charge can be transmitted at e,D via the Andreev reflection process: An electron coming from the normal side is reflected as a hole and a Cooper pair is transferred to the superconductor. 2 This should have important consequences for the energy distribution of quasiparticles in a short normal bridge connected to two superconducting reservoirs. Here we assume that the length L of the bridge is larger than the thermal diffusion length LT5A\D/2pkBT which governs the penetration of Cooper pairs into the normal wire. For L.LT the supercurrent through the structure is exponentially weak.
