Recent advances in 2D transition metal dichalcogenide-based photodetectors: a review

“…49 Two-dimensional TMDs along with a large bandgap can overwhelm the shortcomings of Gr, but their photoresponse wavelength limit is restricted from ultraviolet (UV) to near-IR, which can be determined through their bandgap. 50,51 The TMD-based photodetectors showed a slower response due to their considerable trapping effects of the photocarriers. 39 Although extensive research is currently being carried out to investigate the performance of PDs across diverse light regions, the research community experiences several challenges in extruding materials with enhanced photosensitivity.…”

Low-Power Perovskite Neuromorphic Synapse with Enhanced Photon Efficiency for Directional Motion Perception

“…1 However, traditional optoelectronic information systems still face challenges in processing speed and efficiency. 2 The indiscriminate transmission of sensor data to the terminal causes excessive pressure on the processor, 3,4 highlighting the need for novel devices that can acquire, analyze, and respond to external information more efficiently, especially in object detection and tracking scenarios. 5 In the human visual system, nerve cells in the retina encode external visual information into nerve signals and undergo primary classification processes like noise reduction filtering and contour enhancement.…”
