Abstract

Transport, magnetoconductivity, and tunneling were measured in nonsuperconducting Bi2+xSr2-yCuO6 single crystals (x,y0.2), which show two-dimensional localization within the CuO2 planes. The weakening of disorder in the planes is found to be by itself insufficient for superconductivity. Negative magnetoconductivity, evidence for the onset of superconductive pairing, is observed when transport perpendicular to the planes indicates extended states in three dimensions.
