Summary

HIGH QUALITY THIN FILM CUPRATE SUPERCONDUCTORS CAN BE FABRICATED BY DIFFERENT DEPOSITION TECHNIQUES USING A VARIETY OF SUBSTRATES, INCLUDING SRTIO(3), MGO, LAALO(3) AND EVEN SEMICONDUCTING SILICON SINGLE CRYSTALS. BY MEANS OF THE PULSED LASER DEPOSITION TECHNIQUE, THE AUTHOR EXPLORES DIFFERENT SCHEMES FOR CRYSTALLIZATION AND OXYGENATION OF YBCO THIN FILMS SUCH AS FURNACE ANNEALING, RAPID THERMAL ANNEALING AS WELL AS LOW TEMPERATURE PLASMA PROCESSES AND OPTIMIZE THE THIN FILM QUALITY WITH RESPECT TO CRITICAL TEMPERATURE, CRITICAL CURRENT, SURFACE MORPHOLOGY AND STABILITY. FILMSONSRI)AD LAALO(3) SHOW CRITICAL TEMPERATURES OF 90-92 K AND CRITICAL CURRENTS HIGHER THAN 10,000 A/MM2, FILMS DEPOSITED ON BARE SILICON SUFFER FROM LOWER VALUES OF CRITICAL CURRENTS STILL HAVING CRITICAL TEMPERATURES HIGHER THAN 80 K.
