The sharpness and intensity of 2D peak of Graphene in Raman Spectrum will tell you some information about the number of layers

Sridhar Vadahanambi

yes.. read this thread:

Christian Halbig

In general, it is possible.

The 2D peak is sensible in respect to the number of layers. In CVD graphene, the 2D peak has an intensity of 1.5 compared to the G-intensity. In bilayer graphene, the 2D/G band ratio is
