Anomalous temperature dependence of the resistivity of single-wall carbon nanotubes

Abstract
The anomalous behavior of conductivity observed in experiment of single-wall carbon nanotubes is shown to be due to the effects of residual transition metal catalysts residing in close contact with the nanotube walls. A combination of analysis of the density of states based on the tight-binding molecular dynamics and a simple model calculation provides a good description of the resistivity behavior observed in experiment.
