Current-Voltage characteristics of c-axis oriented thin films of YBa2Cu307-x exhibit a power-law dependence with Vo~ICt(T) near the superconducting transition temperature Tc0. The exponent ¢x(T) shows a "universal jump" from 3 to 1 at the Kosterlitz-Thouless transition temperature TKT. The differenc
