Выдержка

The problem of dc current flow through a superconductor-normal metal interface near the critical temperature Tcis considered. The equations for the Green's functions integrated with respect to the variable ζ = v(p-p0) are used to calcuate the resistance of the pure and dirty superconductor S. It is shown that the electric field E decays exponentially over a length {Mathematical expression} within the superconductor and at the S-N interface there is a jump of E [strictly speaking, E varies over the correlation length ζ(T)]; here D is the diffusion coefficient, and Τeis the energy relaxation time. The magnitude of the jump of E is of the order of or less than the value of E at the boundary of the S region. In the case of a pure superconductor this jump is caused by the Andreev reflection of quasiparticles at the S-N interface.
