Abstract
APPLICATIONS OF THIN FILM HIGH T(C) SUPERCONDUCTORS ARE ANTICIPATED IN VARIOUS ELECTRONIC DEVICES SUCH AS IN SENSORS, DETECTORS, MILLIMETER WAVE COMPONENTS AND AS COATINGS ON POWER TRANSMISSION LINES. SEVERAL GROUPS HAVE SUCCESSFULLY DEPOSITED THIN FILMS ON SINGLE CRYSTAL SRTIO(3) AND MGO SUBSTRATES USING CONVENTIONAL TECHNIQUES SUCH AS SPUTTERING AND E-BEAM EVAPORATION. A SIGNIFICIANT STEP TOWARD REALIZING THE POTENTIAL APPLICATION OF THIN FILM HIGH T(C) SUPERCONDUCTOR IN ELECTRONIC DEVICES WILL BE THE FABRICATION OF A JOSEPHSON JUNCTION. THIS PROPOSAL ADDRESSES THE FEASIBILITY OF FABRICATION OF A VERTICAL JOSEPHSON JUNCTION DEVICE USING THIN TANTALUM OXIDE LAYER AS THE TUNNELING DIELECTRIC. THIN FILM SANDWICH STRUCTURE WILL BE DEPOSITED BY MAGNETRON SPUTTER DEPOSITION. THE SANDWICH STRUCTURE WILL BE CHARACTERIZED FOR ITS PHYSICAL AND ELECTRICAL PROPERTIES.
