Novel thermopiles based on modulation-doped AlGaAs/InGaAs heterostructures are proposed and developed for the first time for uncooled IR focal plane array (FPA) image sensor application. The high responsivity R with the high-speed response time τare designed to be 4900 V/W with 110 μs. Based on inte...
