Description
Three-unit-cell thick YBa2Cu3O7-δ (YBCO) films are grown on SrTiO3 (0 0 1) substrates with periodic arrays of single-unit-cell height steps on their surface. A characteristic fault in the YBCO film is generated on each substrate step, as observed by atomic force microscopy. By electrical resistivity measurements, it is shown that this fault serves as a superconducting weak link. Anisotropy in the normal-state resistivity is observed, depending on the current direction parallel or perpendicular to the substrate step.
