Rough interface effects on N-S proximity-contact systems

摘要

We discuss the influence of atomic scale roughness of the interface on the properties of the N-S contact systems. To treat the interface roughness effects we extend our previous quasi-classical theory of the rough surface effect and construct a formal solution for the quasi-classical Green's function. We apply the formulation to N-S systems with two-dimensional anisotropic d_(x~2-y~2) superconductor and calculate the self-consistent pair potential and the density of states at the interface.
