Abstract
In-situ growth of 2-in. diameter superconducting YBa2Cu3O7-x (YBCO) th in films using an excimer KrF pulsed laser has been studied. Films wit h critical transition temperature (T-c,T-0) of 89 +/- 1 K and critical current density (J(c,77K)) in excess of 1 x 10(6) A cm(-2) have been prepared routinely. Uniformity in film thickness of below +/- 15% and film composition of +/- 5% have been measured. The effects of gas nozz le geometry and target evolution during ablation on the superconductin g properties and surface morphology of YBCO thin films have also been investigated.
