本文用分层二维t-J模型研究了高温超导体中的本征约瑟夫森效应。在平均场近似和Gutzwiller近似下，得到了垂直于t-J面流动的直流约瑟夫森电流。我们发现，约瑟夫森电流表现出最大值附近的最佳掺杂区域的掺杂率的函数。
The intrinsic Josephson effect in high- T c superconductors is studied using the layered two-dimensional t - J model. The d.c. Josephson current which flows perpendicular to the t - J planes is obtained within the mean-field approximation and the Gutzwiller approximation. We find that the Josephson current exhibits a maximum near the optimum doping region as a function of the doping rate.
