Hybrid J-Aggregate–Graphene Phototransistor [PDF]

ACS Applied Nano Materials, 2019
J-aggregates are fantastic self-assembled chromophores with a very narrow and extremely sharp absorbance band in the visible and near-infrared spectrum, and hence they have found many exciting applications in nonlinear optics, sensing, optical devices, photography, and lasing. In silver halide photography, for example, they have enormously improved the
