Bolometric photodetectors have been widely investigated and studied since their delicate applications in military, commercial, public, and academic domains. In article number 1904482, Hailin Peng, Xueao Zhang, Shiqiao Qin, and co‐workers report that a Bi2O2Se‐based bolometer shows a high temperature coefficient of resistance (−1.6% K−1), high bolometric coefficient (−31 nA K−1) and high bolometric...
Bi2O2Se is emerging as a photosensitive functional material for optoelectronics, and its photodetection mechanism is mostly considered to be a photoconductive regime in previous reports. Here, the bolometric effect is discovered in Bi2O2Se photodetectors. The coexistence of photoconductive effect and bolometric effect is generally observed in multiwavelength photoresponse measurements and then confirmed...
