Abstract
Motivated by recent discoveries of novel superconductors such as NaxCoO2⋅yH2O and Sr2RuO4, we analyze features of quasiparticle scattering due to impurities and interfaces for possible gapful dx2−y2+idxy and px+ipy Cooper pairing. A bound state appears near a local impurity, and a band of bound states form near an interface. We obtained analytically the bound-state energy, and calculated the space and energy dependent local density of states resolvable by high-resolution scanning tunnelling microscopy. For comparison we also sketch results of impurity and interface states if the pairing is nodal p or d wave.
