Abstract

We report on a new high-resolution optical spectroscopy, coherent phonon measurement, for determining the chiral index of carbon nanotubes. Using femtosecond pump-probe spectroscopy, we demonstrate the real-time observation of lattice vibrations in individualized single-walled carbon nanotubes in an aqueous surfactant solution. Almost all available radial breathing modes in the Fourier transform spectrum from coherent phonon oscillations are well-resolved with less ambiguity in comparison to continuous-wave resonant Raman scattering.
