Two-dimensional thermal conductivity of defect-free single-walled carbon nanotubes

Abstract

Based on the known Debye’s model for heat capacity and on the kinetic model for the phonon heat transfer taking into account the length of nanotube and also of the contribution made by phonon-phonon scattering, a heat conduction model of defect-free single-wall carbon nanotube was proposed. Based on this model, the dependences of the two-dimensional thermal conductivity of defect-free single-wall carbon nanotubes on their length and temperature were defined.
