Evolution of Raman spectra in nitrogen doped graphene

We present systematical Raman studies of nitrogen doped graphene (NG). Defective graphene by Ar+ ion bombardment was also studied for comparison. It was found that the defects/nitrogen dopants in NG are not homogenous. Our results also suggest that the G peak position and I2D/IG ratio cannot be simp...
