Abstract
The quasiparticle current and d.c. Josepshon current in high T-C grain boun dary junctions are calculated taking account of the brodening of the life t ime of the quasiparticle. By properly choosing parameters, a following situ ation is realized, where quasiparticle current has a zero bias conductance peak, while the temperature dependence of the Josepshon current does not sh ow any anomaly at low temperatures.
