Phonons and Thermal Transport in Carbon Nanotube Systems

Abstract

"Due to the combination of a high speed of sound hard optical vibration modes and a large phonon mean free path carbon nanotubes prove to be the most efficient thermal conductors." (D Tornanek, 2005). The stiff sp3 bonds, resulting in a high speed of sound, make monocrystalline diamond one of the best thermal conductors. An unusually high thermal conductance should also be expected in carbon nanotubes, which are held together by even stronger sp2 bonds... The rigidity of nanotubes, combined with a virtual absence of atomic defects or coupling to soft phonon modes of the embedding medium, should make these systems very good candidates for efficient thermal conductors.
