| The results of studies of the transport properties of various superconducting systems, primarily involving Josephson junction devices, are presented. The first study concerns site-disordered arrays of conventional Nb/Au/Nb proximity coupled junctions. A new scaling law is presented in which the current-voltage (IV) curves are shown to condense onto one of two universal curves, indicating that the arrays undergo a Kosterlitz-Thouless (KT) transition. Also presented are magnetic field data taken on the most disordered array which do not display a crossover from two dimensional (2D) to fractal dimensional behavior, as has been observed in 2D percolating wire networks.;Next, the results of transport measurements done on bulk ceramic samples of ;Finally, detailed studies of a novel high T;The 2D arrays of these novel high T... |
