High thermal conductivity materials with low CTE, and high strength and stiffness are required for high thermal flux applications. In addition, if these materials are relatively inexpensive, lightweight and non-toxic, and have low vapor pressure to survive in space-operating environments, they will be attractive candidates for thermal management in aerospace structures. Such materials are urgently ...

This Small Business Innovation Research Phase I program proposes the development of a high thermal conductivity (470-550 W/mK), low coefficient of thermal expansion (5-8 ppm/K), and low weight (2.9-4.3 g/cc) Cu based metal matrix composite material to produce high performance substrates for microelectronics packaging. The proposed MMC system uses copper as the continuous metal matrix and cubic bor ...

Diamond has recently emerged as a promising material for electron field emission due to its unsurpassed properties of low voltage and room temperature operation, operation robustness, simple design, and reproducibility. However, the present diamond cathodes, which are microcrystalline diamond thin films deposited on macro-substrate (mm to cm size ) suffer a few drawbacks. Only 1-10% or less of the ...

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 ...

Ceramic/ceramic composites are high performance structural elements in many military and commercial applications. Cost-effective methods of producing mechanically strong bonds between ceramic composite components during fabrication of complex shapes are critical to achieving next generation performance targets for both industrial (automotive) and military (aerospace) applications. Existing materia ...

Sensors, capacitors, and conducting features such as resistors and capacitors on circuit boards are produced from metal and ceramic powders 1-12 These powders are manufactured by liquid phase precipitation routes which often start with reduction of metal salts or by solid-state routes where solid reactants are mixed, heated and then milled. The solid-state processing is generally repeated several ...

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 ...

Large area electronics are under rapid development given the opportunity they offer to high definition displays and thin film microelectronic devices. Much of the present-day thin film device manufacturing technology is derived from IC fabrication technology. Unfortunately, conventional IC fabrication technology is extremely expensive for large-area electronics. A revolutionary cost reduction in s ...
