| Abstract: | he intrinsic Josephson effects in Tl2Ba2CaCu2O8 thin films have been investigated atdifferent temperatures. The experimental results of I-V characteristics and the temperature dependence of critical currents show that the intrinsic Josephson junctions inTI2Ba2CaCu2O8 thin films are of the SIS type. |
