Abstract
- A microscopic calculation of the Rayleigh scattering cross section and the absorption coefficient for arbitrary single-walled carbon nanotubes is presented. The approach is based on the density matrix formalism combined with the tight-binding band structure. Both Rayleigh and absorption spectra show a characteristic intensity ratio behavior, which can be explained by an interplay of the optical matrix element and the joint density of states.
