摘要：

We study the effect of a nonmagnetic impurity on the relaxation of the charge imbalance in ad-wave superconductor. We compute the electric field as a function of distance in the normal-metal-superconductor junction. while taking into account the effect of the impurity scattering, gap anisotropy, Andreev scattering, and crystal orientation of the order parameter. We compare the results with a highly anisotropic s-wave superconductor and also discuss the effect of the electron-phonon scattering.
