Notes:
The effect of nanosecond pulsed excimer laser irradiation on the particle distribution and density of laser-deposited YBa2Cu3O7 thin films was investigated. High-TC YBa2Cu3O7 superconducting thin films with thicknesses varying from 800 to 2000 A(ring) were deposited on (100) LaAlO3 and (100) yttria stabilized zirconia substrates. The as-deposited films were characterized by a distribution of particles on the film's surface. The effect of controlled low energy density pulses (fluence, E=50–250 mJ/cm2, wavelength λ=248–308 nm, and pulse duration τ=20–45×10−9 s) on these films was investigated. A significant reduction of particles was observed in films after single pulse irradiation at fluences below 150 mJ/cm2. Multiple pulses did not have any further change on the surface morphology. The possible mechanisms for particle removal are also discussed.
