PROXIMITY CONTACT OF SUPERCONDUCTORS WITH ANISOTROPIC FERMI-SURFACE

The proximity tunneling density of states and the order parameter vari ation across the boundary of an NS junction with anisotropic Fermi sur faces are evaluated self consistently in the weak-coupling BCS limit. The induced energy gap of the normal-conducting N layer, which may be measured in the tunneling density of states, is computed in an example , and the results for simple anisotropic Fermi surfaces are compared.
