  Title Evidence for a “brick wall” microstructure in epitaxial YBa 2Cu3Ox films Type Journal Article
  Year 1994 Publication Applied Physics Letters Abbreviated Journal  
  Volume 65 Issue 6 Pages 770-772  
  Keywords  
  Abstract We have measured the in-plane (ab plane) critical current density J c in sputtered, c-axis oriented YBa2Cu3O x films as a function of the oxygen content x. The important reduction of Jc with decreasing x can be explained in terms of a “brick wall” microstructure, where the critical current density is dominated by the coupling strength (along the c axis) between the superconducting CuO 2 planes. Scanning tunneling microscopy images of the film surfaces are consistent with the presence of the brick wall structure, which apparently results from the overlap between terraces belonging to adjacent spiral-shaped islands.
