Abstract
This Letter reports the results of a systematic study of the current-induced noise at the superconducting transition in thin, high-resistivity films of aluminum and tin. Analysis of the noise suggests that the onset of resistance is due to discrete phase slips of magnitude less than . The results are discussed in terms of the vortex unbinding models of the superconducting transition in two dimensions.
