摘要: In this paper, the fringe effect on critical current has been studied systematically by measuring the electric transport characteristics of a Au-film system with diffuse fringe structure. It is found experimentally that, when the fringe effect becomes obvious, the film will exhibit strange I-R charac-teristics, in which exist a balance current and a critical current. We find that the critical exponents are related lo the diffuse fringe structure of the Films. The detailed analysis shows that the character- biles result from the thermionic-activating conductive effect in the diffuse fringe film sytem.
