Abstract
We have investigated transport through a channel with superconducting boundaries where electrons are confined by Andreev reflection. Superconducting phase-sensitive transport is discussed using qualitative arguments. The transfer resistance Rt through the channel as well as the resistance Ri between the injector and the channel have been measured as a function of the phase difference φ between the superconducting boundaries. It is not yet clear that the observed oscillation in resistance can be attributed to quasi-particle phase-sensitive transport. The oscillation amplitude in Rt due to the transmitted current modulation is less than 0.1% in this experiment.
