  2. 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 ...

  4. Evaluation of High Power 6H-SiC Microwave Field-Effect Transistors for High Temperature Operation

    SBC: CREE RESEARCH, INC.            Topic: N/A

    There is an increasing need in many military systems to have solid state microwave devices with higher power capability, higher reliability, and higher operating temperatures. These devices would be important for airborne radar systems, electronic warfare and countermeasure systems, and airborne and space-based communications systems. While conventional semiconductor materials such as SI and GaAs ...

  5. 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 ...

  6. 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 ...

  7. MATERIAL RECYCLING AND WASTE MINIMIZATION BY FREEZE CRYSTAL CORPORATION

    SBC: Ftc Acquisition Corp            Topic: N/A

    This program will demonstrate the applicability of the freeze crystallization (FC) process dirctly to U.S. Air Force environmental managers by, in phase I, (1) finding applications that are well served by this technology, (2) demonstrating the capabilities of the FC process by processing wastes in FTCAC's lab pilot plant facilities, and (3) developing a design for a prototype FC plant that will be ...

  8. Oxidizer Scrubber Solution Recycling by Freeze Crystalliation

    SBC: Ftc Acquisition Corp            Topic: N/A

    When loading nitrogen tetroxide before launching the space shuttle, fugitive N2O4 is absorbed into caustic solutions in a two stage scrubber solution. The second stage of the scrubber has sodium sulfite added to the alkaline scrubbing solution to act as an oxidant scavenger, to improve scrubbing efficiency. The N2O4 oxidant reacts with water and with the sulfite to form acids (neutralized by the a ...

  9. 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 ...

  10. 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 ...
