Thick Film Processes and Their Effects on the Connectivity and Pinning in Thick Film RBCO Coated Conductors

T. G. Holesinger

Los Alamos National Laboratory, Los Alamos, NM 87545 U.S.A.

High critical current densities (J_c) in YBa₂Cu₃O_y (YBCO) coated conductors depend directly upon the connectivity and defect density within the films. Hence, one needs to develop methodologies for controllably introducing defect structures that are sufficient for tailoring the superconducting properties while, on the other hand, maintaining high critical current properties over lengths exceeding several hundred meters. Aspects of thick film development for physical and chemical deposition processes will be discussed with respect to the types of defects that can be expected to form and effects of thick film growth on connectivity.
