Figure 2

Schematics of van der Pauw configurations for (a) sheet resistance and (b) Hall effect measurements. (c) Experimental setup of magneto-transport measurements of un-patterned samples in the vdP geometry using AC bias and DC magnetic field. In all the cases, the sample in the schematics is represented by an experimental KPFM map of a CVD graphene sample.
