From: Current status and technological prospect of photodetectors based on two-dimensional materials
Overview of performance metrics of standard and 2D-based photodetector technologies. a Various photodetector technologies plotted against their corresponding responsivity and time response. The top left region corresponds to high gain-bandwidth-product detectors and should be the ultimate performance target of future 2D-based photodetectors. b Plot of the specific detectivity D* of various photodetector technologies versus their absorption onset (bandgap). 2D material-based photodetectors have the potential to address the grand challenge in photodetection towards low-cost, high sensitivity infrared detectors
