WebMonolayer graphene has a single Lorentzian peak as there is only 1 component to the 2D-band. As the layers increase the peak broadens and changes shape. For example, the 2D-band of bilayer graphene has 4 components as there are 4 possible double resonance scattering processes, whilst there is only 1 possible for monolayer graphene.
