Fig. 5: Monolithic integration and performance of the NIR imagers.

a Schematic diagram of monolithically integrating the photodetector with the TFT readout circuit. b Photograph of the used TFT backplane along with its size and pixels. c Microphotograph of a partial view of the used TFT pixel arrays, the scalebar is 100 μm. d Schematic illustration of the NIR imaging system for the imagers. e Imaging of the imager for a designed pattern of “I ♥ SXU” operated at a wavelength of 980 nm (≈11.35 mW cm⁻²). f Image crosstalk as the function of a pixel row with a sharp metallic edge. g MTF of the NIR imager
