Abstract:

THE RECENT DISCOVERY OF PEROVSKITE-LIKE COPPER-OXIDE SUPERCONDUCTORS WITH TRANSITION TEMPERATURES ABOVE LIQUID NITROGEN TEMPERATURES HAS LED TO RENEWED INTEREST IN THE APPLICATION OF SUPERCONDUCTIVITY. THESE NEW YBACUO (YBA[2]CU[3[O[7-X]) MATERIALS OFFER THE OPPORTUNITY TO USE THESE MATERIALS AS DETECTORS MORE CONVENIENTLY THAN THE "CLASSICAL" SUPERCONDUCTORS. THE LARGER ENERGY GAP OF THESE NEW HIGH T(C) MATERIALS ALSO PROVIDE THE OPPORTUNITY TO FABRICATE JOSEPHSON JUNCTION DETECTORS CAPABLE OF SENSING OPTICAL RADIATION AND MUCH LOWER WAVELENGTHS, OFFERING NEW COMPETITION TO PREVIOUS SEMICONDUCTOR IR DECTORS IN THE 10 TO 100 MICROMETER REGION. THE OBJECTIVE OF THE PHASE I AND PHASE II PROPOSAL IS TO DEVELOP I SENSOR BASED ON GRINY JOSEPHSON JUNCTIONS IN YBACUO-TYPE SUPERCONDUCTORS. THE APPROACH OFFERED IN PHASE I IS TO USE BULK YBACUO MATERIALS TO DEMONSTRATE THE FEASIBILITY OF USING THESE GRAINY MATERIALS AS IR DETECTORS. PHASE II WOULD CONCENTRATE ON OPTIMIZING THE PERFORMANCE AND TESTING THESE DEVICES BASED ON THE RESULT OF PHASE I. THEY ARE, IN PRINCIPLE, READILY FABRICATED (BY VIRTUE OF THEIR NATURAL GRAININESS) AND ARE VIEWED TO BE A MOST ATTRACTIVE CHOICE FOR DEVELOPMENT USING THE NEW HIGH T(C) MATERIALS.
