Temperature dependence of excess resistance of the normal metal-superconductor interface
Latyshev Yu.l., Nad' F.Ya.
The temperature dependence of the excess resistance Rc of the normal metal-superconductor interface was obtained by direct measurements. It was found that the temperature dependence varies with decreasing temperature from Re~(l T/Tc) 1/4 to Яе~(1 T/Tc) 3/\ which is attributable to the Andreev reflection of quasiparticles.
