WebTo get further resolution of the nanoscale charge distribution, we acquire higher-magnification images ( L = 1.5 μm, L / N = 12 nm) in a GO flake region ( Figure 4 ). At this magnification, the charge density image ( Figure 4 C) resolves many individual charge domains of radius about 25 nm. The total charge of the individual domains is around ...
