This paper reports on investigations of the junctions made between Pb and polycrystalline Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+x} (BSCCO). The BSCCO surfaces were treated with number of methods including mechanically scraping, plasma sputtering, plasma oxidation, and Br etch before junctions were fabricated. The current-voltage characteristics and dynamic resistance (dV/dI) vs voltage have been measured at both 77K and 4.2K. We observed, among other features, a Pb gap structure similar to that seen in Pb/YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} junctions, a magnetic dependent supercurrent, an asymmetric I-V curve, and narrow resistance peaks.
