Induction linear accelerators that produce energetic heavy ion beams are a prime candidate for power-producing fusion reactors. This project will develop and demonstrate a high vacuum arc ion… more
Abstract:Two approaches are proposed to attack the problems of fixturing process. First, a novel hardware holding system, Dexterous Vise, is proposed. Functionally, a single Dexterous Vise is capable of revealing four faces of the clamped workpiece to the cutting tool without re-fixturing, which actually… more
Abstract:The continued use of arsine gas and/or its derivatives is vital to the manufacture of a wide variety of semiconductor devices. While the use of arsine is growing, it poses serious environmental and safety problems in the industry. New methods must be found that permit the facile trapping and… more
Abstract:Incorporation of cleavage microcracks on otherwise crack free material is a new approach used in the fabrication of some microelectonics devices. This proposal describes the development of a new computer controlled microindenter system for the farication of microcracks on a crystalline substrate.… more
Abstract:The potential applications of microelectromechanical systems (MEMS) have only begun to be recognized. This technology demands thin film materials with exceptional microstructural quality for high performance and processes with high yields. For piezoelectric microactuator applications, thin film… more
Abstract:Multilayer thin films deposited onto Si wafers often exhibit high residual stresses during processing, leading to structural failure and/or electrical breakdown. Traditional scanning x-ray diffraction provides an accurate measurement of complex stress behavior in multilayer structures, but is… more
Abstract:THE UNIQUE PROPERTIES OF SEMICONDUCTING DIAMOND MAY BE EXPLOITED TO CREATE NOVEL, COMPACT, LOW-NOISE PHOTON AND PARTICLE DETECTORS. PHOTOMULTIPLIER TUBES ARE THE DETECTOR OF CHOICE WHEN LIGHT LEVELS ARE LOW OR WHEN THE PROPER SIGNAL MUST BE EXTRACTED FROM A CLUTTERED BACKGROUND. CONTINUOUS DYNODES… more
Abstract:Sensors and control electronics based on SiC offer an opportunity to realize systems with operating temperatures approaching 500 degrees C. The unique high temperature properties and chemical robustness of SiC make it an ideal choice for applications where generic components and sensors need to… more
Abstract:The III-V nitrides have recently emerged as the primary material system for UV/blue light emitters. Higher bandgap energy (Al,Ga)N alloys are currently employed as cladding layers for GaN and (In,Ga)N active region LEDs and laser structures. Lattice mismatch between the cladding and active regions,… more
Abstract:Large power handling systems of 1KW to 150KW are required in a many applications ranging from aerospace to consumer electronics to industrial power systems and transportation. Conventional electronic systems, based on silicon or gallium arsenide devices, require a large number of devices enhanced… more
Abstract:Increasingly strict emissions requirements and the need to increase fuel economy and reduce service intervals have dramatically accelerated the use of monitor and control electronics in engines. traditional methods such as adjusting the air/fuel ratio to optimize catalyst performance are not… more
Abstract:Integration of many different devices on a single silicon carbide (SiC) substrate is necessary to realize the full potential of high temperature or high power devices for markets ranging from industrial and consumer to military systems to transportation power and control. Integration … more
Abstract:A $1B commercial blue optoelectronics industry supplying full color displays, high speed communications systems, and high density optical recording devices will happen. The question is: which technology, II-VI materials, III-V nitrides, or silicon carbide and its alloys, will dominate? Theoretical… more
Abstract:Although imaging in the 8-12 micron spectral region has widespread uses, high background radiation result sin low contrast, and charge storage in SiO2 capacitors limits the signal-to-noise and the upper limit of the dynamic range. A major opportunity exists to increase the performance of IR focal… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
