Comments on "Thermal Conductivity of Nanotubes: Effects of Chirality and Isotope Impurity" [cond-mat/0501194]

Abstract

Based on Zhang and Li's molecular dynamics calculations, the heat conductivity ($\kappa$) of metallic single-wall Carbon nanotubes (SNTs) was incorrectly concluded as mainly influenced by the radius. Apart from that, their isotope effect interpretation on $\kappa (T)$ for the metallic SNTs using solely the phonon scattering mechanism is also highlighted to be incorrect.
