Measurements of the population lifetime of D band and G? band phonons in single-walled carbon nanotubes

Measurements of the population lifetime of D band and G? band phonons in single-walled carbon nanotubes
We report time-resolved incoherent anti-Stokes Raman scattering measurements of the dynamics of the D and G? bands in single-walled carbon nanotubes at excitation energies of 1.51 and 1.63 eV over the temperature range 4–330 K. The measurements indicate that the population lifetimes (1 ps) of the phonons responsible for the D band are dependent on nanotube type. The temperature dependencies are consistent with anharmonic decay of the phonons into one low (<190 cm–1) and one high energy phonon.

Abstract

We report time-resolved incoherent anti-Stokes Raman scattering measurements of the dynamics of the D and G? bands in single-walled carbon nanotubes at excitation energies of 1.51 and 1.63 eV over the temperature range 4–330 K. The measurements indicate that the population lifetimes (1 ps) of the phonons responsible for the D band are dependent on nanotube type. The temperature dependencies are consistent with anharmonic decay of the phonons into one low (<190 cm–1) and one high energy phonon.
