NOVA Scientific, Inc., teamed with the Electronics Group of Oak Ridge National Laboratory, proposes to construct very large area Microchannel Plate neutron detectors. The applications of these much larger format detectors will serve an exceptionally broad range of government agencies from neutron scattering detectors for DOE to nuclear material panel detectors for NNSA, and ultimately to nuclear m ...

Single-crystal aluminum nitride substrates will be used for epitaxial growth of GaN by hydride vapor phase epitaxy (HVPE). The relatively close match in crystal structure, in chemical compatibility, and in thermal expansion should allow much high quality(and much thicker) GaN layers to be grown. HVPE will allow these GaN epitaxial layers to grown cost effectively.Extremely high power microwave ...

Hybrid Technologies (HT, Amherst, NY) in cooperation with the Institute for Lasers, Photonics and Biophotonics (ILPB) at the State University of New York at Buffalo proposes to develop new bulk glass-photopolymer materials and investigate the feasibilityof using them for high efficiency, permanent, highly wavelength selective holographic gratings needed for Dense Wavelength Division Multiplexing ( ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...

In the remanufacturing industry (for example the remanufacture of floor care products such as vacuum cleaners) the integration of cost-effective materials recovery technology would provide for the optimum recycling of plastics. Presently, reject plastic parts that cannot be re-used in remanufactured products are disposed. This project will demonstrate the commercial viability of an integrated re ...

A random access, solid-state, optical cross-switch capable of 770 channel discrimination in the telecommunications C-band is designed and proven as an alternative to current thin-film WDM devices and as a mechanically robust alternative tomicroelectromechanical (MEMS) WDM devices. The device may be used in multiplexing (mux), demultiplexing (demux), or complete cross-switch configurations, and is ...

AlInGaN-based heterostructures have demonstrated unmatched versatility in optical and electronic applications. In particular, AlGaN/GaN high electron mobility transistors (HEMTs) are the leading candidates for realizing ultra-high frequency, low-noiseand high-power amplifiers. The addition of indium to the composition of these HEMTs is expected to dramatically improve their performance. We prop ...

Fiber optical transmission is increasingly applied to computer network, secure telecommunication systems, military aircraft, and even in missile guidance systems. 1300 nm vertical cavity surface-emitting lasers (VCSEL) are becoming a prefered technologyfor transceivers in short- and medium-haul, enterprise and metro data network. There is significant interest in using diluted nitride GaInNAs as ac ...

The wide-bandgap semiconductors GaN and SiC hold great promise for high temperature and highpower electronic devices. This is due to the attractive properties these materials possess, such as wide energy bandgaps, high breakdown fields, high thermalconductivities, and high saturated electron velocities. In addition, GaN and SiC have adequate electron mobilities and can readily be doped n and p ty ...
