Abstract

Micro-Raman spectra of single-walled carbon nanotubes, graphite bulk crystals, one-layer and two-layer graphenes are investigated in detail. The structure of Davydov multiplets in the energy spectra of electronic states of one-layer and two-layer graphenes and Bernal graphite bulk crystals is established. The energy spectra of vibrational and electronic states of nanotubes and graphite bulk crystals are shown to be described by the dispersion curves, which pairwise joint at points A of the Brillouin zones of these structures. The forms of stationary elastic waves in single-walled carbon nanotubes at Γ and A points of their Brillouin zones and in one-layer and two-layer graphenes and bulk graphite at Γ, K, and M points of their Brillouin zones are analytically calculated.
