Abstract:Although technologies derived under the Integrated High Performance Turbine Engine Technology (IHPTET) initiative should result in higher performance of gas turbine engines, the durability of engine components continues to be one of the most important design issues which impacts their affordability… more
Abstract:HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS,… more
Abstract:DUE TO ITS UNIQUE PROPERTIES AND ITS ABILITY TO BE PROCESSED ANALOGOUSLY TO SILICON, SILICON CARBIDE (SIC) WILL BE AN IMPORTANT HIGH TEMPERATURE, HIGH POWER, AND HIGH FREQUENCY ELECTRONIC MATERIAL. THE BARRIER TO THIS DEVELOPING TECHNOLOGY WAS THE AVAILABILITY OF 6H-SIC SUBSTRATES. HOWEVER, THESE… more
Abstract:CHEMICAL VAPOR DEPOSITION (CVD) OF LEAD-BASED FERROELECTRICS SUCH AS LEAD TITANATE, LEAD ZIRCONATE TITANATE (PZT), AND LEAD LANTHANUM ZIRCONATE TITANATE (PLZT), IS THE MOST PROMISING MANUFACTURING METHOD FOR A WIDE VARIETY OF NEXT GENERATION ELECTRONIC DEVICES INCLUDING RADIATION-HARD NON-VOLATILE… more
Abstract:Aircraft landing gear, and wheels in particular, are subjected to heavy loads during service. Controlled surface compressive stresses help to improve the fatigue life by reducing the probability of crack initiation and propagation from the wheel surface. Manufacturers such as Allied Signal… more

Abstract:The ongoing explosion of microwave radar and communications systems calls for improvement in electronically scanned antennas (ESAs). However, current ESAs crafted from multiple individual elements are extremely expensive. Forming an antenna with integrated scanning and impedance matching elements… more
Abstract:The III-V nitrides, (Al, In, Ga)N, are promising materials for high temperature, high power and high frequency devices due to the wide bandgaps, high electron saturation velocity and high electronic mobility transistor (HEMT) structures available in this alloy system. These devices would find… more
Abstract:Virtual displays have tremendous potential in defense applications such as virtual reality training, battlefield support, and information systems. Full color displays require red, blue, and green LED arrays of which only red is commercially available. This program teams ATMI, a recognized leader in… more

This project will develop new techniques for in-situ nondestructive measurements of key mechanical properties of reactor pressure vessels (RPVs) subjected to irradiation embrittlement. The effort… more
Abstract:Increasing thermal and power loads in circuitry demand electrical components which can operate at temperatures up to 400 C and beyond . A combination of high bandgap semiconductors and improved dielectrics is needed to solve this problem. ATMI has maj or programs in production of both SiC/GaN… more
Abstract:In this program we will develop narrow linewidth AlGaN Bragg reflector lasers suitable as injection seeds for solid-state W lasers in the range of 280 to 330 nm. These systems are compact, light weight, and low-power consuming and ideal for airborne lidar systems. Bragg reflector lasers have never… more
Abstract:Photodiodes have high efficiency since the absorption region thickness is large. However, no GaN p-i-n photodiodes have been reported due to the difficulty in achieving low background doped GaN. This Phase I program seeks to determine the increase in quantum efficiency achievable by the use of a… more
Abstract:Commercially viable silicon carbide device manufacturing processes depend on an ability to grow'low defect density epitaxial layers. Low defect density epitaxial layers start with pristine SiC substrate surfaces. Epi-ready pristine SiC surfaces are not commercially available. The results of… 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.
