a Schematic illustration of the coassembly of GO and perylene at the interface. b Photograph of the assembled film on a SiO2/Si substrate under daylight. AFM images of c the upper surface and d the bottom surface of the film. e, f Polarization optical microscope images of the upper layer from the heterostructure.
