THIS PROJECT PROPOSES TO EXPLORE THE USE OF A WIDE BANDGAP SEMICONDUCTOR TO MAKE DEVICES CAPABLE OF OPERATING AT TEMPERATURES OF AT LEAST 500 0C. PN JUNCTIONS WILL BW FABRICATED. THE MAJOR THRUST WILL BE THE STUDY OF ELECTRODE TECHNOLOGY TO MAKE OHMIC CONTACTS THAT ARE STABLE AT HIGH TEMPERATURE AND IN THE PRESENCE OF AN ELECTRIC BIAS. THE APPROPRIATE METALLIZATION MUST RESIST BOTH THERMAL DIFFUSI ...

Q-DOT proposes to develop a wide bandwidth, monolithic, analog-to-digital converter (ADC) using advanced silicon-germanium (SiGe) BiCMOS technology. State-of-the-art commercially available, wide band ADCs are represented by the MAX108 at 8 bits and 1.5Gs/s with 2.2 GHz signal bandwidth (the fastest commercially available ADC); and, the AD9410, a 210 Ms/s, 10-bit ADC with 500 MHz signal bandwidth ( ...

This proposal describes a program to determine the feasibility of forming an entirely new class of optical structures: wide-angle resonant cavities (WARCs). A WARC-structured light emitting diode would have "laser-like" high efficiency and modulation speeds. A WARC-structured vertical cavity laser would have low threshold currents and extremely high speeds. The device characteristics sought are si ...

A PIPELINE STRATEGY FOR MAN-MACHINE DECISION MODULES HAS BEEN DEVELOPED. IT HAS HIGHER OVERALL DECISION PERFORMANCE THAN THE SINGLE DECISION MODULE STRATEGY, AND IS MORE COMPUTATIONALLY EFFICIENT THAN THE MULTIPLE MODULE APPROACH. IT PROVIDES A FRAMEWORK FOR CONTROLLED CONSTRUCTION OF ORTHOGONAL DECISION MODULES, AND DIFFERS FROM THE MULTIPLE MODULE APPROACH BECAUSE EACH MODULE ONLY OPERATES ON DA ...

Harmonia proposes an innovative approach to improving product quality and reducing time and cost of transitioning prototypes to production. This approach uses the User Interface Markup Language (UIML), an open specification language being standardized byOASIS, as a user interface design language that can be rendered to usability prototypes, tactical HCI code, and object model representations. Th ...

We propose to design and develop an advanced GPS/INS integrated system for anti-jam and high dynamics conditions. Integration between GPS and INS will be performed in a federated sense using ultra-tight coupling. CRS has developed a novel GPS developmentsystem consisting of integrated software tools and hardware modules. These tools allow simulation and real-time implementation in a single step ...

OPTICS USED IN SENSORS OR MISSILE SYSTEMS ARE MADE FROM SAPPHIRE, OR SILICON CARBIDE BECAUSE OF THEIR EXCELLENT OPTICAL OR INSULATING PROPERTIES, THEIR INERT, AND THEIR ABILITY TO RESIST HARSH ENVIRONMENTS. POLISHING SAPPHIRE BY MECHANICAL OR MECHANOCHEMICAL METHODS INDUCES RESIDUAL DAMAGE AND LIMITS THE OVERALL SURFACE ROUGHNESS (USUALLY AROUND 1 MICROINCH). THIS ROUGHNESS PRODUCES SCATTERING CEN ...

Silicon carbide materials will revolutionize semiconductor devices for military and commercial markets. The material's wide bandgap, high electric field breakdown, high thermal conductivity give SiC capabilities that far exceed those of silicon or gallium arsenide. Despite significant progress in silicon carbide development, fundamental defects--most prominently micropipes--persist. If SiC is to s ...
