Tunneling into d-wave superconductors: Effects of interface spin-orbit coupling
arXiv:1007.4483 · doi:10.1103/PhysRevB.82.184501
Abstract
Tunneling conductance of a clean normal metal/d-wave superconductor junction is studied by using the extended Blonder-Tinkham-Klapwijk formalism. We show that the conductance is significantly affected by the interface spin-orbit coupling of the Rashba type, which is inevitably present due to the asymmetry of the junction.
