Abstract

We applied an infrared- (IR-) laser-assisted chemical vapor deposition technique to YBa2Cu3O7-δ (YBCO) film fabrication in order to enhance the deposition rate to one suitable for commercial applications. IR-laser illumination during deposition effectively suppressed outgrowth of a-axis oriented grains, which strongly diminish the film's current-carrying capacity. As a result, high-performance YBCO films with critical current densities of greater than 1 × 106 A cm -2 were successfully obtained at high deposition rates of up to 58 μm h-1 (∼1 μm min-1) by this method.
