Relationship between Rtot and Vg of the graphene on SiO2 device fabricated using TEM grids was measured (a) in water and (b) in ethanol, as well as in air. Also, Rtot and Vg of the graphene on SiO2 device fabricated using e-beam lithography was measured (c) in water and (d) in ethanol. All measurements were performed at room temperature.
