The current-voltage characteristics of linear chains of submicron Josephson tunnel junctions
The recent experimental results on granular superconducting films have suggested an universal sheet resistance threshold of 6.4 k$\Omega$/square, below which all films become superconducting with decreasing temperature, and above which all films become insulating with decreasing temperature. At the critical sheet resistance of 6.4 k$\Omega$/square, the conductance of the granular films exhibited unusual quasi-reentrant behavior with decreasing temperature.
