ZnO has many inherent advantages over current materials used to fabricate UV LEDs and lasers in that it is a more efficient light emitter, has better radiation hardness, and can easily be fabricated in bulk single crystals. Uniquely, this project will utilize the high purity, 2-inch diameter ZnO single crystals developed by ZN Technology as substrates on which to epitaxially grow ZnO pn junction ...

High-efficiency UV detectors will be developed in the Phase II program with ZnO and its alloy (ZnBeO). ZnO and ZnBeO are a very suitable material for fabrication of high-speed, high-detectivity, and radiation-hard UV detectors due to their unique structural, electrical and optical properties. The proposing company (MOXtronics) has shown the feasibility of fabricating new ZnO p-i-n UV detectors in ...

ZnO has many inherent advantages over current materials used to fabricate UV LEDs and lasers. It is a highly efficient light emitter due to the excitonic nature of the emission.

76088S The currently-used transparent conducting oxide electrode for OLED construction is very expensive. It is desired not only to lower the electrode material cost, but also to lower its electrical resistivity and increase its optical transmissiveness. In order to improve the cost and efficiency of OLEDs for solid-state lighting, this project will develop an alternate transparent conducting ...

PhotoSense proposes to develop a ruggedized luminescent oxygen sensor compatible with aircraft fuel tanks and other harsh, flammable environments. Diverse military and commercial applications exist for an oxygen sensor operating in jet fuel and other explosive vapors over a wide range of temperatures (-65F to 140F) and pressures (2psi to 16psi) while maintaining accuracy over 10 years of use. Ig ...

This work proposes to develop a zero boil off (ZBO) dewar using a two-stage pulse-tube cooler together with two innovative, continuous-flow cooling loops and an actively cooled shield. While a number of cryogenic refrigeration systems may be considered for such applications, none offers the same potential for low vibration, high reliability, and high efficiency as the pulse tube. The continuous-fl ...
