  • METHOD FOR FORMING RF-PROPERTIES-OPTIMIZED COMPOSITIONS OF (RE) Ba2Cu3O7-delta THIN FILM SUPERCONDUCTORS
    Publication number: 20160218269
    Abstract: The films of this invention are high temperature superconducting (HTS) thin films specifically optimized for microwave and RF applications. In particular, this invention focuses on compositions with a significant deviation from the 1:2:3 stoichiometry in order to create the films optimized for microwave/RF applications. The RF/microwave HTS applications require the HTS thin films to have superior microwave properties, specifically low surface resistance, Rs, and highly linear surface reactance, Xs, i.e. high JIMD. As such, the invention is characterized in terms of its physical composition, surface morphology, superconducting properties, and performance characteristics of microwave circuits made from these films.
    Type: Application
