Laser stimulated thermal conductivity in chiral carbon nanotube

Abstract

An investigation of laser stimulated thermal conductivity in chiral CNT is presented. The thermal conductivity of a chiral CNT is calculated using a tractable analytical approach. This is done by solving the Boltzmann transport equation with energy dispersion relation obtained in the tight binding approximation. The electron thermal conductivity along the circumferential χc and axial χz are obtained. The results obtained are numerically analyzed and both χc and χz are found to oscillate in the presence of laser radiations. We have also noted that the laser source caused a drastic reduction in the both χc and χz values
