Influence of localization effects in a normal metal on the properties of SNS junction
Spivak B. Z., Khmel'nitskii D. E.
It is shown that quantum corrections to the conductivity of a normal metal, located between two superconductors, depend on the difference in the phases of the order parameter in the superconductors. If a voltage is applied to the SNS junction, then the current through the junction oscillates at twice the Josephson frequency. A boundary condition is proposed for the "cooperon" at the boundary between the normal metal and the superconductor.
