Critical-temperature reduction (Formula presented) is considered for a thin film of a superconductor (S) with a rough surface covered by a thick layer of a normal metal (N). The value of (Formula presented) induced by the roughness of the SN interface can be much higher than (Formula presented) for a film with a plain surface if the superconductor is extremely anisotropic.
