Abstract
It is known that global superconductivity (wherein the resistance of a film vanishes) is destroyed when the film resistance exceeds 6.5 kΩ per square. A number of features of the data (low-temperature plateaus, exponential growth of low-temperature resistance with normal-state resistance, enhancement of resistance below in high resistance films) can be explained by a simple model of localization, assuming sample inhomogeneity and shorting effects by isolated superconducting grains. In addition, a transition from weak to strong localization in the normal state is clearly identified.
