In amorphous, nongranular, thin films of Nb₃Ge, the temperature dependence of the resistance and the current-voltage relation have been investigated at temperatures below the experimentally determined thermodynamic transition. This temperature-dependent resistance is compared to several theories which predict flux-flow resistance below the BCS transition temperature due to thermally excited vortex pairs.
