| | In this talk we investigate the thermal rectification phenomenon in a single-wall mass graded carbon nanotube by molecular dynamics simulation. Second generation Brenner potential has been used to model the inter-atomic carbon interaction and fixed boundary conditions have been taken into account. The dependence of the rectification factor R on the temperature, nanotube diameter and mass gradient was obtained. It is shown that by increasing the temperature, the rectification decreases whereas by increasing other parameters such as the mass gradient, diameter and tube's length, it increases.
