Title: Uncooled Radiation Hard Large Area SiC X-ray and EUV Detectors and 2D Arrays
Agency: NASA
Contract: NNG05CA19C
Award Amount: $600,000.00


This project seeks to design, fabricate, characterize and commercialize large area, uncooled and radiative hard 4H-SiC EUV ? soft X-ray detectors capable of ultra low noise photon counting. The detector design and advanced processing technologies combined with the unique material property of 4H-SiC are expected to lead to orders of magnitude improvements to the performance of large area solid state detectors including much lower noise due to the wide bandgap and substantially improved lifetime due to the greatly increased radiation tolerance in comparison to state-of-the-art solid state EUV-soft X-ray detector technologies. In Phase II, detectors and 2D arrays will be designed and fabricated. Eight batches will be fabricated with different detector sizes and different active abs thicknesses. Concentration will be focused on achieving very low dark current and high quantum efficiency based on a novel design. The fabricated detectors and 2D arrays with different optical window sizes will be characterized, including dark current, forward current ideality factor, quantum efficiency. The dominant source and mechanism of the dark current will be investigated to help identify approaches to further reduce the dark current in the privately funded Phase III which will be concentrating on pushing up the yield over 3" wafer for commercialization within one year after the completion of Phase II.
