FIG. 1.

SWCNT phonon spectrum for AC tubes and (5,5) and the breathing mode is labeled B. Kohn anomalies are not considered in this work.

FIG. 2.

Relaxation times for 12 initial hot optical phonons varying in polarization (), transverse wavevector (zone center ZC or zone edge ZE), and axial wavevector (). Error bars show standard deviations for an ensemble of 200 simulations. Standard deviation ranges at are shown with hatched lines.

FIG. 3.

Relaxation times for initial hot phonon LOZE at as a function of diameter and tube chirality (AC or ZZ), .

Image of FIG. 4.
FIG. 4.

Count of final states after scattering during the decay of an SWCNT LOZE initial hot phonon with initial wave vector . Each graphitic-type polarization mode is labeled in the upper -axis; for each mode there are six sub-branches proceeding left to right in the -axis.
