The red-shifting of 2D Raman band position of graphene is attributed to doping of graphene??
4 answers
The red-shifting of the 2D Raman band position in graphene is not solely attributed to doping. Research indicates that the Raman 2D peak position and splitting can be correlated with charge density variations in graphene, with lower charge densities resulting in larger 2D peak-splits. Additionally, the interplay between graphene and its supporting substrate, such as Cu grains, can also influence the Raman bands. For instance, (110) Cu grains exhibit anomalous shifts in the graphene 2D Raman band due to weak graphene-Cu coupling, impacting the Raman scattering processes. Therefore, while doping can play a role in the Raman characteristics of graphene, factors like charge density variations and substrate interactions also significantly contribute to the observed red-shifting of the 2D Raman band position.
