Abstract:

The Stanford Center for Research on Superconductivity and Superconductive Electronics is currently focused on developing techniques for producing increasingly improved films and multilayers of the high-temperature superconductors, studying their physical properties and using these films and multilayers in device physics studies. In general the thin film synthesis work leads the way. Once a given film or multilayer structure can be made reasonably routinely, the emphasis shifts to studying the physical properties and device physics of these structures and on to the next level of film quality or multilayer complexity. Our most advanced thin films synthesis work in the past year has involved developing techniques to deposit a-axis and c-axis YBCOPBCO superlattices and related structures. The in situ feature is desireable because no solid state reactions with accompanying changes in volume, morphology, etc., that degrade the quality of the film involved. RRH
