  1. A Phototransistor Based on GaN-A1xGa1-xN Heterostructure

    SBC: Apa Optics, Inc.            Topic: N/A

    We propose to demonstrate the feasibility of fabricating a phototransistor using the A1xGa1-xN material system. The proposed phototransitor is based on a GaN-A1xGa1-xN heterojunction which exhibits a 2-D electron gas conduction when a bias is applied on the source-drain terminals. The device is maintained in a nominally OFF state by applying a reverse bias voltage on the gate terminal. With optica ...

  3. Novel Doping Sources for III-V Molecular Beam Epitaxy

    SBC: Essential Research, Inc.            Topic: N/A

    The developement of four different doping sources for use within an MBE system is proposed. Two high purity, high uniformity sources for use with Carbon, and two such sources will be developed for use with Tellurium. The purity of the species produced by each cell will be studied with a Residual Gas Analyzer. Recommendations concerning the use of these cells in a solid source MBE system will be su ...

  4. Storage Heater Material Optimization

    SBC: Fluidyne Engineering Corp.            Topic: N/A

    High temperature storage heaters are needed to provide clean, hot air for aerodynamic and propulsion testing of hypersonic vehicles. Vitiation heaters do not properly simulate the vehicle flight conditions, thus limiting the ability to develop tomorrow's aircraft in a timely manner. Yttria-zirconia storage heater development work was sponsored by the Air Force in the 1960's, but did not produce an ...

  5. ENVIRONMENTAL ENGINEERING RESEARCH

    SBC: H.V. Setty Enterprises, Inc.            Topic: N/A

    The development of a low-cost reliable and long-life novel, electrochemical sensor with multigas sensing capability that can detect 10 ppb of toxic gases and vapors with a response time of 30 seconds is proposed. During phase I, we will develop an electrochemical amperometric sensor cell with a three electrode configuration using nonaqueous aprotic electrolyte solution. This nonaqueous electrolyte ...

  6. DEVELOPMENT OF MEMBRANE SAMPLING SYSTEM TO CONCENTRATE TOXIC ENVIRONMENTAL COMPOUNDS FOR RAMAN SPECTROSCOPY ANALYSIS

    SBC: NeoMecs Inc.            Topic: N/A

    IN THE LONGER TERM, THE RESULTS OF THIS RESEARCH COULD LEAD TO IMPROVE D METHODS AND EQUIPMENT FOR SAMPLING, CONCENTRATING AND ANALYZING TRACES OF HAZARDOUS CHEMICALS IN GROUNDWATER. SPECIFIC OBJECTIVES: 1) PREPARE HOLLOW FIBER MEMBRANES BY SURFACE MODIFICATION. 2) ASSEMBLE MEMBRANE MODULES. 3) TEST MODULES FOR PERMEABILITY TO SELECTED PESTICIDES IN WATER SOLUTION. 4) SELECT APPROPRIATE SOLVENTS F ...

  7. IN-PLACE DATA RECORDER FOR AIRCRAFT TRANSPARENCY SYSTEMS

    SBC: NVE CORP. (FORMERLY NONVOLATILE ELECTRONICS, INC.            Topic: N/A

    BY UTILIZMG MAGNETORESISTIVE RANDOM ACCESS MEMORY (MRAM) IN COMBINATION WITH SENSOR TECHNOLOGIES, NVE WILL DESIGN A COMPLETE DATA GATHERING AND STORAGE SYSTEM FOR AIRCRAFT TRANSPARENCY SYSTEMS WHICH WILL RECORD OPERATIONAL DATA DURING FLIGHT AS WELL AS DURING SHIPPING AND STORAGE. FABRICATION AND ASSEMBLY INFORMATION CAN EITHER BE ENTERED AFTER MANUFACTURING OPERATIONS ARE COMPLETE, OR DURING THE ...

  8. A SEMI-AUTOMATED DOWNGRADER FOR MLS NETWORK GUARDS

    SBC: SECURE COMPUTING CORP.            Topic: N/A

    TO BE SUCCESSFUL THE C31 COMMUNITY HAS A NEED FOR SECURE, EFFICIENT COMPUTER SYSTEMS THAT SUPPORT THEIR MISSION. AN IMPORTANT ELEMENT OF CURRENT SYSTEMS IS THE NERWORK GUARD. SEVERAL GUARDS CURRENTLY DEPLOYED ALLOW TRANSFERS OF INFORMATION FROM LOW SECURITY LEVELS TO HIGH SECURITY LEVELS, BUT NO GENERAL PURPOSE GUARDS ARE AVAILABLE THAT ALLOW TRANSFERS FROM HIGH TO LOW. SCTC PROPOSES TO DEVELOP A ...

  9. Carbon and Tellurium Doping Sources for Molecular Beam Epitaxy (MBE)

    SBC: SVT ASSOCIATES, INCORPORATED            Topic: N/A

    We propose two novel sources for improved carbon and tellurium dopants in MBE growth for III-V compounds semiconductors where heavy doping is required. The compact carbon source is electron beam heated and has a very fast thermal response. It is expected that increased monatomic carbon species in the flux would improve the dopant behavior. The tellurium source produces ionized species which would ...

  10. Quantum Well and Superlattice IR Detector Development

    SBC: SVT ASSOCIATES, INCORPORATED            Topic: N/A

    Strained layer superlattices of GaInSb/InAs have been shown to have many desirable optical and transport properties, especially for VLWIR (>12um) detection. We propose to explore its fabrication and device applications by growing on polar orientations. It is expected the piezoelectric effect would be beneficially extend its IR response to longer wavelength. This will also make material parameters ...
