2.5 Phonon Properties

The phonon dispersion relations of SW-CNTs can be calculated using zone folding [29], tight-binding methods[37,38,39,40], density functional theory [41,42,43,44,45,46,47,48,49], and symmetry-adapted models [50,51,52,53,54]. The phonon dispersion relations of SW-CNTs can be understood by zone folding of the phonon dispersion branches of graphene.
