基于黑磷油墨薄膜的中波红外探测器阵列
Mid-wavelength infrared detector array based on black phosphorus ink thin film
摘要
Abstract
Mid-wavelength infrared(MWIR)imaging technology plays a crucial role in aerospace,medical diag-nostics,and autonomous driving.Van der Waals material black phosphorus(BP)exhibits exceptionally high car-rier mobility and an ideal direct bandgap,making it a proven candidate for high-performance room-temperature MWIR sensing.However,the stringent growth conditions and anisotropic growth characteristics restrict the devel-opment of BP optoelectronic devices to small-scale laboratory demonstrations.Therefore,there is an urgent need to develop large-scale,uniform,and high-performance BP photodetector arrays.This study employed a room temperature preparation technique to deposit a large-area,uniform,low-oxidation BP ink film onto thin-film tran-sistors,resulting in the development of a 64×64 high-performance MWIR snapshot photodetector array.The room temperature ink preparation process effectively prevents the oxidation of BP during fabrication,achieving an oxidation loss as low as 1.12%.In addition,a gradient centrifugation strategy was employed to optimize the later-al size and thickness distribution of the nanosheets in the BP ink,thereby facilitating the transport of charge carri-ers.The BP ink film array demonstrated a high photoresponsivity of 4.52 mA/W in the MWIR range,with pixel light response non-uniformity as low as 10.1%.This study presents a new approach for advancing large-scale MWIR imaging technology.关键词
