Thermal properties of defective fullerene.

We have investigated the thermal conductivity of defective fullerene (C by using the nonequilibrium molecular dynamics (MD) method. It is found that the thermal conductivity of C with one defect is lower than the thermal conductivity of perfect C. However, double defects in C have either positive or negative influence on the thermal conductivity, which depends on the positions of the defects. The phonon spectra of perfect and defective C are also provided to give corresponding supports. Our results can be extended to long C chains, which is helpful for the thermal management of C.
