graphene g peak
I've taken alot of Raman spectra of CVD graphene. On a few occasions I see that the G-peak has a left shoulder on it (~ 1550 cm-1). Does anybody know why ... ,Where the D and G bands of Thin films of Tio2/Graphene will lie on the wave ... The G band is the first-order Raman band of all sp2 hybridized carbon materials.
