摘要：

We report current-voltage measurements on arrays of high-T(c) intrinsic Josephson junctions showing a temperature dependence of the first critical current which is different from that of subsequent critical currents for an array with sub-micron dimensions. This can be explained by the change in the impedance seen by other array-junctions once one junction switches out of the supercurrent state, resulting in a switching-off of thermally activated phase-diffusion.
