    Fully integrated CMOS-compatible photodetector with color selectivity and intrinsic gain
    (2017-10-31) Zheng, Bob Yi; Wang, Yumin; Halas, Nancy J.; Nordlander, Peter; Rice University; United States Patent and Trademark Office
    A metal-semiconductor-metal photodetecting device and method of manufacturing a metal-semiconductor-metal photodetecting device that includes a p-type silicon substrate with an oxide layer disposed on the p-type silicon substrate. Schotty junctions are disposed adjacent to the oxide layer on the p-type silicon substrate and a plasmonic grating disposed on the oxide layer. The plasmonic grating provides wavelength range selectability for the photodetecting device.
