Constructed Wetland System for Treatment of Washrack Effluent

Not Available The primary goal of Phase I work will be to demonstrate ZnO p-n junction technology to form a ZnO UV LED. The technology is enabled by Cermet¿s proven ability to grow high quality, ZnO bulk substrates of 1 square centimeter area, and proven ZnO MOCVD technology. Zinc oxide MOCVD technology will be obtained by Cermet from an MOCVD industry leader. N-type and p-type ZnO films will be deposited on homoepitaxial substrates to form the p-n junction. An additional structure could include p-type films on n-type bulk substrates to form the p-n junction. Device design and material characterization will be enhanced through the use of an internationally recognized compound semiconductor expert. The successful completion of Phase I goals will demonstrate ZnO UV diodes and practical UV LEDs in Phase II. By building on Phase II results, future, more complex, devices will include ZnO UV laser diodes and detectors
