Аннотация

In this paper we have proposed a wavelet-based approach to study peak components fitting to the Raman 2D band of few layer graphene. As a result of the Continuous Wavelet Transform application peak components of the Raman 2D band are visualized and their number and peak frequencies are determined. It is found that there are four and five peak components of the 2D band for bilayer and trilayer graphene stacked in the Bernal (ABA) configuration respectively. In the case of tetralayer graphene with the rhombohedral (ABC) stacking there are also five peak components of the Raman 2D band. The peak frequencies of detected components are in good agreement with the experimental data.
