We report tunneling measurements of the superconducting energy gaps in YBa.Cu307 and Bi2Sr.CaCthO 8 using b~eak junctions. The differential conductance d/fdV at T = 4.2 K shows no leakage around zero ba~s, while the t,,q~ -dge peaks m d//dV are somewhat broadened compared to the simple BCS density o

Systemauc conductivity lluctuatmn measurements are reported for polycryatalhne YBa2Cu3OT\_ 8 and singlecrystal Bi2Sr2CaCu208. Gaussian and criucal regimes are observed For both systems, the crmcal exponents are consistent with s-wave pairmg.
Thin films of YBa2Cu30~ and Bi2Sr2CaCu2Os were deposited by high-pressure oxygen sputtering and laser ablation, respectively, on bicrystailine substrates of SrTiO3 with angles of 10,24,36 and 45 degrees. The microstructure of the grain boundary in the substrate and in the film was characterized by t
