Global phase coherence in two-dimensional granular superconductors

Experimental evidence is presented from studies of the onset of superconductivity in ultrathin Sn films which implies that the sheet resistance is the only relevant variable in determining the onset of global phase coherence. This result is also found by a theoretical argument involving both the pha...
