Investigation of thermal conductivity of single-wall carbon nanotubes
Jafari Mahmoud, Vaezzadeh Majid, Mansouri Momhamad, Hajnorouzi Abazar
In this paper, the thermal conductivity of Single-wall carbon nanotubes
(SWCNTs) is determined by lattice vibrations (phonons) and free elections.
The thermal conductivity of SWCNTs is modeled up to 8-300 K and the observed
deviations in K-T figures of SWCNTs are explained in terms of phonon
vibrations models. An suitable theoretical model is shown for thermal
conductivity behavior with respect to temperature and is generalized for
experimental results. This model enables us to calculate thermal conductivity
SWNTs and Thermal Potential Energy (TPE).
