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

Interfacial thermal conductance between silicon and a vertical carbon nanotube
TL;DR: In this paper, the authors used molecular simulations to evaluate thermal resistance between crystalline silicon and a vertically oriented carbon nanotube (CNT) and found that without chemical bonds between CNT and Si the thermal resistance is high and its values are consistent with that measured in experiment on vertical CNT arrays.

Optical absorption and thermal transport of individual suspended carbon nanotube bundles.
TL;DR: A focused laser beam is used to heat individual single-walled carbon nanotube bundles bridging two suspended microthermometers and the thermal conductance of the bundle is obtained with the additional measurement of the temperature rise of the nanotubes in the laser spot from shifts in the Raman G band frequency.

Z.L. Wang,Dawei Tang,Xiaobo Li,Xinghua Zheng,Wei Gang Zhang,Li Xin Zheng,Yuntian Zhu,Ai Zi Jin,Hai Fang Yang,Chang Zhi Gu +9 more
TL;DR: In this paper, the authors measured the length-dependent thermal conductivities of individual SWCNTs on a Si substrate using a four-pad 3 omega method, which is consistent with a theoretical prediction that considers higher order three-phonon processes.

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.
