MANY OF THE COMMERCIAL SENSORS IN USE (OR UNDER DEVELOPMENT) ARE BASED IN METAL-OXIDE CERAMIC MATERIALS. METAL-OXIDES OFFER SPECIAL ADVANTAGES BECAUSE OF THEIR CHEMICAL AND THERMAL STABILITY, FAST RESPONSE TIMES, AND SENSITIVITY TO ELECTROCHEMICAL CHANGES. THERE ARE REPORTED CASES THAT SHOW ADSORPTION OF WATER IN METAL OXIDES OFTEN ENHANCING BOTH THE SURFACE CONDUCTIVITY AND DIELECTRIC PROPERTIES ...

InP based heterojunction bipolar transistors (HBTs) exhibit proven potential for use in high performance digital integrated circuits and discrete microwave components. For high speed applications, it is desirable to utilize structures that have been designed to promote high levels of nonequilibrium electron transport as this allows realization of higher electron velocities than possible for diffus ...

Current rare earth permanent magnets have proven to be in adequate for higher temperatures (300-500_C) military and Air Force applications. Development of permanent magnetic materials which can operate in high temperature regime will enable design of simpler, more efficient magnetic systems. The More Electric Aircraft (MEA) concept pursued by the US Air Force drives this need. We propose a novel p ...

Revolutionary high power electronics based on new materials such as SiC and GaN hold promise in numerous applications in power electronics, control and distribution circuits, hybrid drive-train automobiles, ''more electric" aircraft (avionics) and next generation battleships. These high-temperature materials require novel high-temperature (> 1500_C) processing schemes for improving the efficiency ...

A novel technological approach was recently devised by Sumi Tech engineers to fabricate multilayer electronic components, which enables the manufacture of devices with very high volumetric efficiency and reliability. Inexpensive electrode materials such as copper, or aluminum are potential candidates, since the process takes place at relatively low ambient temperature (e.g., less than 400 C), thus ...

We propose to develop a novel and ambitious tool for large-scale development: a fourth-generation computer language (4GL) based upon an object-oriented generalization of the hierarchical block diagram paradigm, with powerful integrated simulation capabilities. Developers would assemble a prototype in a connect-the-blocks visual programming environment, test and evaluate it via simulation, then ite ...

The properties of single-crystal silicon carbide are such that electronics devices from this material have demonstrated remarkable performance characteristics. Despite the material's promise, the material has not yet found acceptance in mainstream device markets because of the material's high cost, among other reasons. This Phase I SBIR proposes an SiC source powder with unique properties which wi ...

Passive broadband limiter with high response speed is a promising device used to protect optical sensor against determined attack. Lam Optics, Inc. (LOI) proposes to investigate the development of a novel optical limiter using commercially available materials. The optical limiter operates on the following principles. These are beam self-defocusing and total internal reflection induced by absorptio ...

The performance of existing resistors is unsatisfactory for high frequency, small foot print, low noise electronic and communication applications. These technology limitations can be addressed with resistors prepared from proprietary band-gap engineered, near-molecular scale materials. This project, during Phase I, will establish the proof-of-concept that commercially useful resistor arrays can be ...
