Thermal conductance and thermopower of an individual single-wall carbon nanotube.
TLDR
It is observed that the thermal conductance of a 2.76-microm-long individual suspended single-wall carbon nanotube (SWCNT) was very close to the calculated ballistic thermal conductances of a 1-nm-diameter SWCNT without showing signatures of phonon-phonon Umklapp scattering for temperatures between 110 and 300 K.Abstract:
We have observed experimentally that the thermal conductance of a 2.76-μm-long individual suspended single-wall carbon nanotube (SWCNT) was very close to the calculated ballistic thermal conductance of a 1-nm-diameter SWCNT without showing signatures of phonon−phonon Umklapp scattering for temperatures between 110 and 300 K. Although the observed thermopower of the SWCNT can be attributed to a linear diffusion contribution and a constant phonon drag effect, there could be an additional contact effect.read more

Green's Function Methods for Phonon Transport Through Nano-Contacts
TL;DR: The phonon transport problem can be formulated at the length scale of interest as discussed by the authors, and at the bottom end of the scale is the atomistic description, which can be used to extract parameters that are needed for coarser-grained descriptions like the equation of phonon radiative transfer.

Thermal conductivity of carbon nanotube—polyamide-6,6 nanocomposites: Reverse non-equilibrium molecular dynamics simulations
TL;DR: The thermal conductivity of composites of carbon nanotubes and polyamide-6,6 has been investigated using reverse non-equilibrium molecular dynamics simulations in a full atomistic resolution and it is found that the composites have thermal conductivities, which are only moderately larger than that of pure polyamide.

Unusually High Thermal Conductivity of Carbon Nanotubes
TL;DR: An unusually high value, lambda approximately 6600 W/m K, is suggested for an isolated (10,10) nanotube at room temperature, comparable to the thermal conductivity of a hypothetical isolated graphene monolayer or diamond.

Extreme oxygen sensitivity of electronic properties of carbon nanotubes
TL;DR: The results, although demonstrating that nanotubes could find use as sensitive chemical gas sensors, likewise indicate that many supposedly intrinsic properties measured on as-prepared nanotube may be severely compromised by extrinsic air exposure effects.
