- Abstract
Bi 2O 2Se, broadband photodetector, infrared/terahertz detection, THz imaging Keywords: Bi 2O 2Se; broadband photodetector; infrared/terahertz detection; THz imaging EN Bi 2O 2Se broadband photodetector infrared/terahertz detection THz imaging 1 1 1 04/03/21 20210401 NES 210401 In article number 2009554, Man Luo, Peng Wang, Zhiming Huang, and co-workers demonstrate a room-temperature 2D Bi SB 2 sb O SB 2 sb Se photodetector with ultrafast (476 ns) and ultralow noise (0.2 pW Hz SP -1/2 sp ) for broadband detection. While in the THz region, the nonequilibrium electrons are injected from the metal electrodes to Bi SB 2 sb O SB 2 sb Se by the electromagnetic induced well under the THz wave.
