Using these relationships, we can thus generate a plot of w2D vs wG with superimposed strain and carrier concentration axes (Fig. ). Here we draw e in increments of 0.1% and 𝑛 in increments of 0.5 x 10 13 cm -2 . Note that 𝑛 in our case is the hole concentration, so we consider the graphene to be p-or hole-doped. A 𝜀-𝑛 plot with the zero strain and doping axes along with the data corresponding to unstrained and undoped graphene (i.e. the origin of the 𝜀-𝑛 plot) is shown in Fig. . The e-beam chemistry experiments for this study were performed at a beam energy of 1 kV and water vapor pressure of 5 Pa, and the electron dose was varied from 1343 -91000 µC/cm 2 .
