Abstract
The Kosterlitz-Thouless theory for the electrical dissipation in the high temperature superconductors predicts scaling of the current voltage characteristics above the phase transition temperature but not below. We give an expression for the universal scaling curve which provides an excellent fit to data for epitaxial YBa2Cu3O7 thin films taken in zero applied magnetic field. Surprisingly, the expression also provides an excellent fit to data taken in finite magnetic fields.
