Contact resistance as a measure of the superconducting order parameter

  • M. K. Chien

We have shown experimentally that the electrical contact resistance between a thin copper wire and a bulk superconductor contains a small contribution that varies with temperature below Tc. The observed temperature dependence is always close to that of the energy gap in the superconductor.
