Fig. 4. (a) Conductance variation of graphene as a function of time while sweeping VEG from 0 to 0.8 V. (b) EFM (VEFM) image of graphene after oxidation process (2) in (a), upon applying VDS = −1 V. (c) Conductance variation of graphene as a function of time while sweeping VEG from 0 to −1.80 V. (d) EFM (VEFM) image of graphene after oxidation process (3) in (c), upon applying VDS = −1 V. The white dashed arrow denotes undesired residues on graphene. (e) Topography image of graphene after oxidation process (3) in (c). The white dashed arrow denotes undesired residues on graphene.
