WebBlack phosphorus is also a good material for the photodetection thanks to its wide bandgap (0.3–1.9 eV) that makes the dark current small compared to graphene. The reason that makes BP a best suit for photodetection applications is that it has high charge carrier mobility even at room temperature in contrast with 2D TMDCs (Xia et al., 2014b). WebApr 5, 2024 · Near-infrared (NIR) photodetection has a wide range of applications including biomedical imaging, remote temperature sensing, and so on. Pyro-phototronic effect has been investigated in the field of NIR detection.

WebApr 4, 2024 · Hot electron photodetection provides a powerful platform for photosensing beyond the bandgap of a semiconductor. High-performing hot electron photodetection has been reported in 2D transition metal dichalcogenide material-based devices without the support of plasmonic metal nanostructures but with planar metal electrodes. Photodetectors, also called photosensors, are sensors of light or other electromagnetic radiation. There is a wide variety of photodetectors which may be classified by mechanism of detection, such as photoelectric or photochemical effects, or by various performance metrics, such as spectral response.
