“…However, the inferior light absorption of single atomic layer graphene limits the phototransistor performance 10 . 2D/semiconductor heterojunctions are expected to break the electron-hole occupation symmetry, giving rise to the generation of photocurrents, including in quantum dot-enhanced structures 11,12 , stacked 2D heterojunction structures [13][14][15][16][17] , 2D planar structures 18,19 , dual photogating phototransistors 20 , waveguide-integrated enhanced structures 21,22 , bilayer-enhanced structures 23,24 , and even nanographite structures 25,26 . In particular, some typical 2D localized field methods incorporating 2D, organic, perovskite, and Dirac materials were subsequently proposed to realize high-performance phototransistors 23,24,[27][28][29][30][31][32][33] .…”
