Heterojunction bilayers serving as a charge transporting interlayer reduce the dark current and enhance photomultiplication in organic shortwave infrared photodetectors
Abstract
This work modifies the charge-transporting layer in organic photodiodes to a heterojunction bilayer. The bilayer design facilitates photomultiplication and suppresses the dark current to enhance detectivity and contrast in upconversion imagers.
