Abstract

Laser deposition is widely used to fabricate thin-films of the YBa2Cu3O7−δ superconductor due to its ease of operation and its reproducibility. The films thus formed do not require post-deposition annealing to be superconducting. The processing route involves many variables which would be expected to exert an influence on the early stages of the film growth and thereby the final microstructure. The parameters which have been varied are the laser energy, laser pulse repetition rate and laser wavelength. The films have been examined using transmission electron microscopy (TEM) in order to determine the film orientation, composition and microstructure.
