Abstract

Electrical transport properties of c-axis-oriented Tl2Ba2CaCu2O8 thin films have been examined within the context of the Kosterlitz-Thouless (KT) model. The nonlinear current versus voltage and resistivity versus magnetic field characteristics below the KT transition temperature (Tc=99.0 K), together with the exponential inverse-square-root temperature dependence of the resistivity just above Tc, were consistent with each other and with the theory. The parametrization of the resistivity data well above the transition by Aslamazov-Larkin theory was also consistent with that of the KT theory.
