WebFigure 2 shows the (calculated) phonon dispersion of graphene in the high frequency range. It is easy to identify the parts of the dispersion which are responsible for the G and 2D bands. The former originates from the E 2g in-plane phonon at the Γ point where the longitudinal optical (LO) and transverse optical (TO) branches touch each other. The 2D … WebThe zero-phonon line and the phonon sideband jointly constitute the line shape of individual light absorbing and emitting molecules (chromophores) embedded into a …

As temperature increases, the harmonic approximation (in which phonons are non-interacting) becomes increasingly worse, and anharmonic phonon-phonon interactions become important. These interactions change with temperature, and lead to a renormalization of phonon frequencies with temperature.
