【 摘 要 】

We present self-consistent calculations of supercurrent flows in a realistic tilt grain boundary. We obtain the current-phase characteristics in both s-wave and d-wave superconductors. We do this self-consistently within the framework of the Bogoliubov-de Gennes equations, using a realistic microscopic model of the grain boundary. This yields the s- and d-wave superconductor order parameters in the vicinity of the boundary and the respective quasiparticle local density of states. [S0163-1829(99)00529-9].
