Abstract
We present experimental results on electrical measurements of evaporat ed thin lead films (inverse swiss cheese model) and ion-milled thin fi lms (swiss cheese model) at liquid-helium temperatures near the superc onductor-insulator percolation threshold. We provide evidence for the nonuniversality of the critical exponents for the critical current in two dimensions for the two systems studied, in good agreement with the oretical results.
