It is seen that the deviation of the Andreev reflection coefficient (for E > Δ) from ideal Andreev reflection. increases as the angle of incidence and that the deviation becomes greater as the mismatch at the interface is increased. © 1988.Mahidol UniversityPhysics and AstronomyArticleSCOPUS10.1016/0375-9601(88)90214-9
