A Theoretical Evaluation of Temperature Dependent Thermal Conductivity of Carbon Nanotube

L. P. Mishra and L. K. Mishra

Using the theoretical formalism of J. Hone (Dekker encyclopedia of Nano science and Nanotechnology, 2004), we have evaluated the temperature dependent thermal conductivity of isolated SWNT, 2D-graphene sheet, 3D-graphite and single MWNT. From these evaluations, it shows that the thermal properties of carbon nanotubes are dominated by phonons. The results also show 1-D quantization of phonon band structure. Our theoretical results indicate that nanotube composite materials may be useful for thermal management applications.
