Aspects of the Thermal Conductivity of Nanotubes

ORAL

Abstract

We have measured the thermal conductivity of individual multiwalled carbon and boron nitride nanotubes using a microfabricated suspended device. The structure of the measured nanotubes also has been characterized by using a transmission electron microscope. We have found that the thermal conductivity of an isotopically pure BN nanotube is comparable to that of a carbon nanotube with the same diameter. The temperature dependence, the effect of deformation, and localized defects on the nanotubes' thermal transport will also be presented.
