ZnO Based UV Detector

"The goal of this project is to demonstrate the feasibility of growing solar blind UV photodetectors made of zinc oxide. The primary goal of Phase I will be to demonstrate the growth of high quality homoepitaxial thin films of pure and alloyed ZnO usingCermet's MOCVD reactor and in-house fabricated ZnO substrates. Films will be analyzed using x-ray diffraction, PL, and electrical measurements. BMDO will benefit from this program by having a source of light and compact UV detectors unlike the present Sibased detectors that require bulky band filters. This technology will produce homoepitaxially grown ZnO-based solar blind UV photodetectors, which can be used for misssile plume detection, solar astronomy, intersatellite communications, and combustionengineering."
