Pulsed laser deposition of dielectric and superconducting materials: Mechanisms and applications

The laser ablation method is suitable for the formation of metal oxide thin films, such as dielectric materials and high T/sub c/ superconductors. This is because the laser beam comes from outside the film formation chamber and therefore oxygen pressure can be chosen as a desired value for the growth of thin films. The author prepares PbTiO/sub 3/ thin films, SrTiO/sub 3/-BaTiO/sub 3/ dielectric strained superlattices, BaCaCuO superconducting thin films and AuBaCuO superconducting superlattices.
