摘要: We study analytically the local density of states in a disordered normal-metal wire (N) at ballistic distance to superconductor (S). Our calculation is based on scattering-matrix approach, which concerns for wave-function localization normal metal, and extends beyond conventional semiclassical theory Usadel Eilenberger equations. also analyze how finite transparency NS interface modifies spectral proximity effect demonstrate that our results agree dirty diffusive limit with those obtained from equation.
