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 \chi_c and axial \chi_z are obtained. The results obtained are numerically analyzed and both \chi_c and \chi_z 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 \chi_c and \chi_z values.
