The thermal conductivity and thermoelectric power of a single carbon nanotube were measured using a microfabricated suspended device. The observed thermal conductivity is more than 3000 W/K m at room temperature, which is 2 orders of magnitude higher than the estimation from previous experiments that used macroscopic mat samples. The temperature dependence of the thermal conductivity of nanotubes exhibits a peak at 320 K due to the onset of umklapp phonon scattering. The measured thermoelectric…

Thermal conductance and thermopower of an individual single-wall carbon nanotube.
We have observed experimentally 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
Ballistic thermal and electrical conductance measurements on individual multiwall carbon nanotubes
We report thermal measurements on individual carbon nanotubes using a temperature sensing scanned microscope probe. An arc-grown bundle of multiwalled nanotubes (MWNTs) is mechanically attached to a
Thermal conductivity of individual silicon nanowires
The thermal conductivities of individual single crystalline intrinsic Si nanowires with diameters of 22, 37, 56, and 115 nm were measured using a microfabricated suspended device over a temperature
Optical measurement of thermal transport in suspended carbon nanotubes
Thermal transport in carbon nanotubes is explored using different laser powers to heat suspended single-walled carbon nanotubes ∼5μm in length. The temperature change along the length of a nanotube
Anomalous thermal conductivity in multiwalled carbon nanotubes with impurities and short-range order
Low-temperature thermal conductivity and thermopower of multiwalled carbon nanotubes considered within a bundle of nanotubes are calculated taking into account multiple scattering of electrons on the
Diameter and Temperature Dependence of Thermal Conductivity of Single-Walled Carbon Nanotubes
Temperature and diameter dependence of the thermal conductivity of several armchair single-walled carbon nanotubes (SWNTs) are studied by nonequilibrium molecular dynamics method with Brenner II
Length-dependent thermal conductivity of an individual single-wall carbon nanotube
The thermal conductivity of single-wall carbon nanotubes (SWCNTs) is predicted to increase with length, but this has never been proved experimentally because of limitations in previous measurement
Dependencies of the thermal conductivity of individual single-walled carbon nanotubes
This work is aimed at assessing the sensitivity of carbon nanotube (CNT) thermal conductivity to physical and numerical parameters owing to its wide variation in the literature. CNTs of various


Nanotechnology is the set of technologies that enables the manipulation, study or exploitation of very small (typically less than 100 nanometres) structures and systems. To put this into perspective,
A prototype probability package named APPL (A Probability Programming Language) is presented that can be used to manipulate random variables and examples illustrate its use.
