| Exciton
scattering from impurities and acoustic phonons |
| We study scattering of excitons from impurities and acoustic phonons in carbon nanotubes. In carbon nanotubes, electron-hole symmetry exists. Therefore, scattering of electrons and that of holes for excitons cancel with each other and scattering of excitons are substantially suppressed. |
 |
| Energy dependence of energy broadening for excitons caused by scattering from long-range impurities. Energy broadening for the exciton ground state (red line) vanishes below the band edge for the first excited exciton. |
