It is clear from the data in Fig. that the threshold doses causing the inflection points, or the transition between a strain-dominated to a doping-dominated regime, depend on the type of graphene. The fact that the threshold is an order of magnitude higher for exfoliated graphene could be ascribed to its lower overall defect density (Fig. ). Based on the discussion above, the higher inflection point can also be attributed to the higher hole density at the inflection point (~0.4 x 10 13 cm 2 ), and, consequently the lower Fermi level in exfoliated graphene. But the overall similarities in the dose-dependent behavior of both CVD and exfoliated graphene highlight the potential to pattern, functionalize and dope different graphene samples in a controlled manner.
