Abstract

In crystals of the single-layer cuprate Bi2+xSr2-yCuO6±δ, x ∼ 0.1, y ∼ 0.1 (BSCO), the ab-plane resistivity is linear in temperature and the ρ{variant}c/ρ{variant}ab resistivity anisotropy is 105. The tunneling conductance is close to being a linear function of the bias voltage. Screening measurements show evidence of non-uniform superconductivity. X-ray diffraction indicates superlattice structure approaching commensurate periodicity.
