Abstract
We report voltage noise studies on thin tin films in the superconducting transition region to understand the mechanism of the excess noises observed in the transition. Temperature and I-V characteristics studies suggest evidence of a Kosterlitz-Thouless transition for the thin Sn films studied. A correlation of the onset of rapid increases of noise with the power law in I-V points to the dominant vortex contribution to the excess noises, consistent with the characteristic \sqrt{V} dependence of the spectral power of the noise.
