Penetration of an electrical field into a superconductor
The extra resistance of the superconducting-normal interface has been studied. Near the transition point this resistance is determined from a weak but long-range electric field within the superconductor. At low temperatures the electric field increases logarithmically near the interface for sufficiently clean superconductors. In this case the extra resistance is determined from an increase of the electric field over that of the normal metal.
