Abstract
Square arrays of one million Josephson junctions have been fabricated using the Selective Niobium Anodization Process (SNAP). The arrays consist of 2.5 micron square Josephson junctions on a square lattice with a spacing of 29 microns. Clear evidence of a Kosterlitz-Thouless transition has been found in measurements of current-voltage charcteristics and resistance as a function of temperature. Measurements of the resistance vs magnetic field exhibit minima at fields corresponding to both one and one-half of a flux quantum in a fundamental cell.
