Many factors in the PECVD determine the VG growth and the final product VG structure. The substrate and precursor in the PECVD are believed to be the two dominant factors in the VG synthesis. In addition, several other factors such as plasma source and power, etching rate, surface temperature, and plasma pre-treatment can also affect the final VG structure [1]. The unique synthesis conditions and the distinctive morphological properties of VG also hinder the direct use of theories that have been successfully applied in describing the growth of other structurally-aligned nanomaterials.
44] which describes the relation among the in-plane sp2 crystallite size La, the excitation energy of laser source EL, and I(D)/I(G): La (nm) = 560 ID EL4 IG −1 . 28 for dc glow PECVD (excitation 633 nm laser) [7]. 1. It seems that high-intensity plasmas tend to produce VG nanosheets with a high degree of graphitization (relatively low I(D)/I(G) values). However, one should be very careful to make a general conclusion on which plasma source is the best choice with a simple comparison of I(D)/I(G) values.

Reprinted with permission from [3]. 3 Raman Spectroscopy of VG 31 Most studies on Raman spectra of VG were focused on the shift and the full width at half maximum (FWHM) of G and G′ peaks (sometime includes D and D′ peaks as well [33]) as well as the intensity ratio of D peak-to-G peak I(D)/I(G). Generally, a higher I(D)/I(G) value and an increased FWHM value of the bands suggest smaller crystalline grains as well as a smaller inter-defect distance [38].
