本文研究了d波超导体中粗糙表面的理论模型，它适用于电子被覆盖表面的杂质层散射的任意强度的一般情况。在杂质层与d波超导体的界面上，导出了准经典Eilenberger方程的边界条件。将该模型应用于d波约瑟夫森结表面态密度和临界电流的自洽计算。(C)1999年美国物理研究所。
A theoretical model of a rough surface in a d-wave superconductor is studied for the general case of arbitrary strength of electron scattering by an impurity layer covering the surface. Boundary conditions for quasiclassical Eilenberger equations are derived at the interface between the impurity layer and the d-wave superconductor. The model is applied to the self-consistent calculation of the surface density of states and the critical current in d-wave Josephson junctions. (C) 1999 American Institute of Physics.
