Fig. shows the G and 2D peal frequencies of CVD graphene patterned with various doses that are color-coded from blue to red data points from minimum to maximum electron dose (1343 -91000 µC/cm 2 ). The G and 2D peak frequencies prior to electron beam exposure (as-transferred graphene) are plotted in the 𝜀-𝑛 plot in Fig. . We note that, prior to the application of e-beam chemistry, the graphene experienced a compressive strain ~0.17 % and had a hole concentration of ~0.5 x 10 13 cm 2 . This could be attributed to the presence of PMMA residue on the graphene surface due to the transfer process from the growth substrate (Cu foil)
