进一步发展了非常规超导体间约瑟夫森隧道结的唯象。与s波超导体相反，对于d波超导体，描述势垒的隧道矩阵元素的方向依赖性是相关的。我们找到了完整的I-V特性，并对这些结的电学性质进行了评论。它们敏感地依赖于超导体的相对取向。I-V特性不同于正常的S波RSJ样行为。
The phenomenology of Josephson tunnel junctions between unconventional superconductors is developed further. In contrast to s-wave superconductors, for d-wave superconductors the direction dependence of the tunnel matrix elements that describe the barrier is relevant. We find the full I-V characteristics and comment on the thermodynamical properties of these junctions. They depend sensitively on the relative orientation of the superconductors. The I-V characteristics differ from the normal s-wave RSJ-like behavior.
