Proximity effect in dirty normal metals attachedto p and d wave superconductors Original Research Article

The conductance in dirty normal metal/superconductor junctions is numerically studied using the recursive Green function method. The proximity effect in dirty normal metals attached to superconductors depends strongly on the pairing symmetries in superconductors because of a zero-energy state forming at junction interfaces. We show the anomalous proximity effect in a px wave junctions.
