Raman and infrared properties and layer dependence of the phonon dispersions in multilayered graphene
Raman and infrared properties and layer dependence of the phonon dispersions in multilayered graphene
The symmetry group analysis is applied to classify the phonon modes of $N$-stacked graphene layers (NSGLs) with $AB$ and $AA$ stacking, particularly their infrared and Raman properties. The dispersions of various phonon modes are calculated in a multilayer vibrational model, which is generalized from the lattice vibrational potentials of graphene …
