Fig. 3. (a) Conductance (red line) modulation of SLG induced redox cycle by applied VEG= −1.9 V~0.0 V (black line) in sulfuric acid (1 M). Here A and B indicate the initial and post-initial redox cycle areas. Steps (1), (2) and (3) indicate the conductance variation for the electloyte gating, oxidation and reduction steps, respectively.
