78072S III-V nitride-based, high brightness, UV and visible light emitting diodes (LEDs) are of a great interest for general illumination, but the low light output efficiencies of current high brightness LEDs are still inadequate. A key material issue preventing the achievement of higher light… More

Nitride-based, high-brightness, ultraviolet, visible, and white light emitting diodes are candidate devices for replacing incandescent light bulbs and fluorescent light fixtures in general illumination applications, due to their tremendous energy saving potential, long lifetime, and high efficiency.… More

Tellurium-doped single-crystal ZnSe, or ZnSe(Te), is an important material for fabricating the radiation detectors needed for nuclear physics research. To date, there is no efficient crystal growth technique for producing high-quality, large-diameter, ZnSe single crystals. This project will… More

This Small Business Innovation Research Phase I research project will investigate a novel sublimation crystal growth technique for producing large diameter, high quality zinc sulfide (ZnS) single crystal substrates suitable for fabricating specific UltraViolet (UV) detectors. These UV detectors that… More
