- Statistical preparation and characterization of Bi-based superconducting thin films C. Falcony Guajardo F. Morales J. Araujo Osorio M. Jergel E. Díaz Valdés Física, Astronomía y Matemáticas based films film processing film properties Superconducting Bi experimental design Bi-Pb-Sr-Ca-Cu-O/MgO thin films were prepared by deposition of an aerosol from aqueous nitrate solutions. To preparethe samples, an experimental design was applied to investigate the influence of nine different variables upon synthesis ofsuperconducting phases. Within this design, the influence of chemical composition of the nitrate solutions and theprecursor thermal treatment upon formation of superconducting phases were studied. The Tc values of the samples wereused as a quantitative parameter to analyze and optimize various parameters studied in the film preparation. The analysisrevealed a significant influence of the Bi and/or Bi/Pb content as well as that of Cu and thermal treatment parameters.Results from XRD, SEM, EDS and Tc measurements showed correlation between the film preparation conditions, filmchemical composition and the formation of superconducting phases 2000 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94201004 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
