a 3D schematic of the RAO array, which shows a simple structure of each pixel. b Optical image of the RAO array. c Scanning transmission electron microscopic characterization, which shows the rippled interface and the monolayer MoS2. d Raman spectra of the selected 64 MDR phototransistors. e Color mapping of the Raman peak of the selected 64 MDR phototransistors according to the position. f Dynamic evolution of NV-PPC and NV-NPC with a single 10 ms optical pulse. The orange region represents the duration of the optical pulse. g, h Mechanism of NV-PPC and NV-NPC with enhanced electron mobility. The yellow and blue spheres represent the hole and electron, respectively. The underline represents the natural hole-trapping center. Source data are provided as a Source Data file.
