本文在平均场近似下,用路径积分方法,对由超导-阵列-超导结(S-G-S)组成的隧道结的Josephson特性进行了研究。在中间阵列层有耦合和没有耦合的情形下,分别得到了Josephson电流与温度,位相差和结参数的关系。Under the mean-field approximation, the Josephson tunnelling of superconductor-grain-superconductor junction is analyzed in this paper by using the path-integral formulation. For the cases with coupling and without coupling between the grains, the temperature deperdence of Josephson critical current Ic and the phase dependence of Josephson current I are obtained.
