High-performance MoS₂-based infrared photodetector induced by the photogating effect

Recently, Professor Qi Weihong of Northwestern Polytechnical University and Academician Liu Weimin of Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, found that nickel nanoparticle-modified defective molybdenum disulfide can form a photogating effect, which can greatly improve the infrared photodetection performance of the device.
