The non-Gaussian component of resistance fluctuations is found to be sensitive to film thickness close to the transition, which allows us to distinguish between mean field and Berezinskii-Kosterlitz-Thouless (BKT) type superconducting transitions. The extent of non-Gaussianity was found to be bounded by the BKT and mean field transition temperatures and depend strongly on the roughness and structural inhomogeneity of t","authors_text":"Arindam Ghosh, Aveek bid, John Jesudasan, Kazi Rafsanjani Amin, Mintu Mondal, Pratap Raychaudhuri, R.
