摘要：

We numerically study the de Josephson current in d-wave superconductor/normal metal/d-wave superconductor junctions by using the recursive Green function method. The Josephson current is sensitive to the orientation angle between the crystalline axis of the high-T-c superconductors and the normal of the junction interface. It was pointed out that the ensemble average of the Josephson current, (J), vanishes when the orientation angle is pi/4 and the normal metal is in the diffusive transport regime. We show in this paper that (J) disappears even when the normal metal is in the quasi-ballistic transport regime. (C) 2002 Elsevier Science B.V. All rights reserved.
