title: Coherent phonon dynamics in single-walled carbon nanotubes studied by time-frequency two-dimensional coherent anti-stokes Raman scattering spectroscopy.
abstract: Coherent phonon dynamics in single-walled carbon nanotubes were studied using broadband coherent anti-Stokes Raman scattering microscopy in time-frequency domain. Zone-center G-phonons were coherently created by optical excitation with the relaxation time of 1.1 +/- 0.1 ps, while zone-boundary D-phonons showed incoherent behavior, indicating electron-phonon, electron-defect, and phonon-phonon interactions in semiconducting nanotubes.
