a Comparison of the detectivity and detection range among reported room temperature-operated mid-wave infrared (MWIR) photodetectors based on 2D materials and conventional materials11,12,13,15,16. The theoretical limits of D* calculated for the photodetectors operating under background-limited infrared performance (BLIP) in photovoltaic (PV) mode, photoconductive (PC) mode, and thermal infrared (TIR) mode are shown as black, red, and blue dotted lines, respectively. Tbg and FOV represent background temperature and field of review. b Comparison of the detectivity and response speed among reported room temperature-operated photodetectors based on 2D materials with MWIR (3–6 µm) responses11,12,13,15,16,30,31,32,33,34,35.
