Extensive research has been done on the thermal conductivity of single-wall carbon nanotubes, both experimentally and by use of molecular dynamics simulations. However, the research on the effects of the physical size of the carbon nanotube on thermal conductivity is lacking. The following simulations were performed using lammps molecular dynamics software in order to observe the thermal conductivity of a single-wall carbon nanotube at varying lengths and diameters. The nemd method was employed to allow the carbon nanotube to equilibrate before computing thermal conductivity. Thermal conductivities for three lengths and two diameters have been recorded, each case having results for temperatures ranging from 50 to 500 degrees K. The results show an expected trend, though somewhat undocumented by current research. These results also show that changes in length and diameter affect the temperature dependent thermal conductivity of the nanotubes.
