拉曼只是其中一种表征手段，可以结合AFM或者TEM看看啊

we set a range of the G to 2D peak ratio from 0.7 to 1.3 and the fwhm of the 2D peak from45 to 60 cm-1 to estimate the bilayer coverage.Those that have a G to 2D peak ratio lower than 0.7 and fwhm of 2D peak lower than 45 cm-1 are considered to bemonolayer graphene, and the samples that have a G to 2D peak ratio higher than 1.3 and fwhm of the 2D peak higher than 60 cm-1 are considered few-layer graphene.
