THE PHASE I EFFORT HAS SUCCESSFULLY DEMONSTRATED THAT COMBINING SOL-GEL CHEMISTRY WITH MICROWAVE HEATING CAN RESULT IN THE FABRICATION OF A CERAMIC HIGH TC SUPERCONDUCTOR (HTS) IN ABOUT AN HOUR. SOL-GEL PROCESSING RESULTED IN UNIFORM MICRON-SIZED PRECURSOR POWDERS WITH THE DESIRED STOCHIOMETRY. THIS POWDER WAS SUBSEQUENTLY HEATED FOR 70 MINUTES UNDER SPECIFIC CONDITIONS IN A MODIFIED MICROWAVE OVE ...

N/A

THIS PROJECT WILL RESULT IN HIGH SPEED, LOW COST SPATIAL LIGHT MODULATORS WITH APPLICATIONS INCLUDING OPTICAL PROCESSING, HOLOGRAPHIC MEMORIES, HDTV, AND FLAT-PANEL DISPLAYS. THESE SLMS ARE MICRO-MECHANICAL AND WILL BE FABRICATED ON GLASS OR PLASTIC SUBSTRATES USING EFFICIENT DIELECTRIC MATERIALS AND MATURE, LOW-COST/HIGH VOLUME VACUUM COATING TECHNOLOGIES. CHARACTERISTICS INCLUDE SUB-MICROSECOND ...

N/A

FOSTER-MILLER PROPOSES AN INNOVATIVE TECHNIQUE TO FABRICATE ALL POLYMER, ULTRAHIGH ENERGY DENSITY DOUBLE LAYER CAPACITORS TO MEET SPACE POWER CONDITIONING NEEDS OF THE SDI. THE FOSTER-MILLER APPROACH IS BASED ON INFILTRATING AN IONICALLY CONDUCTING POLYELECTROLYTE WITH THE MONOMER OF AN ELECTRICALLY CONDUCTING POLYMER. THE MONOMER WILL BE POLYMERIZED "IN-SITU" ACHIEVING A HIGH DEGREE OF MOLECULAR ...

THE ADVANTAGES OF SILICON CARBIDE AS A HIGH TEMPERATURE, RADIATION TOLERANT SEMICONDUCTOR MATERIAL ARE WELL KNOWN. UNLIKE COMPARABLE MATERIALS, SUCH AS DIAMOND, PREPARATION OF FUNCTIONAL DEVICES HAS BEEN RELATIVELY STRAIGHT FORWARD WITH THE MAJOR LIMITATION CONTINUING TO BE THE DEFECT DENSITY OF THE SUBSTRATE MATERIAL. A METHOD IS PROPOSED USING ION BEAM SYNTHESIS TO PRODUCE SINGLE CRYSTAL, LOW DE ...

N/A

LASERS OPERATING WITH WAVELENGTHS NEAR 1 MICROMETER MAY HAVE MANY USES FROM LASER RADAR SOURCES TO COMMUNICATIONS LINKS. THEY NEED SOLID-STATE CONSTRUCTION, SMALL SIZE, AND GOOD OUTPUT POWER. THEIR MAIN LIMITATION OF ADEQUATE FREQUENCY STABILITY, LASER SCIENCE, INC. IS DESIGNING AND CONSTRUCTING A FREQUENCY-STABILIZATION SERVO. THIS ADD-ON SERVO WILL CONTROL THE LASER FREQUENCY OF INEXPENSIVE LASE ...

DIAMOND AND CUBIC BORON NITRIDE (CBN) SEMICONDUCTOR DEVICES HAVE THE POTENTIAL TO OPERATE AT HIGHER TEMPERATURE, HIGHER VOLTAGE, AT HIGHER FREQUENCY AND POWER AND UNDER MORE HARSH RADIATION ENVIRONMENT THAN CONVENTIONAL SEMICONDUCTORS, AND AS EMITTERS AND DETECTORS IN THE ULTRA-VIOLET AND VISIBLE. EPITAXIAL DIAMOND/CBN STRUCTURES HOLD THE POTENTIAL FOR FURTHER IMPROVEMENT OF THESE DEVICES AND FOR ...
