Abstract
In-situ growth of 2-in. diameter superconducting YBa2Cu3O7-x (YBCO) thin films using an excimer KrF pulsed laser has been studied. Films with critical transition temperature (Rc,0) of 89±1 K and critical current density (Jc,77K) in excess of 1×106 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 nozzle geometry and target evolution during ablation on the superconducting properties and surface morphology of YBCO thin films have also been investigated.
