The thermal properties of graphene and Ni-coated graphene have been investigated using non-equilibrium molecular dynamics simulations. The results showed that the thermal conductivity of Ni-coated graphene was lower than that of graphene. More excited low-frequency phonons resulted in this decrease. The thermal conductivity of single-layer Ni-coated graphene was 70% of that of graphene, and the thermal...
Defects could be inevitably generated during the growth or the artificial operation of graphene. The existence of structure defects could be influence to excellent properties of graphene. Non-equilibrium molecular dynamics (NEMD) simulations was used to investigate the thermal conductivity of graphene with single vacancy (SV) and stone-wales (SW) defects. Dependence of temperature showed that thermal...

The thermal conductivity of finite-length singlewalled carbon nanotubes (SWCNTs) was investigated using non-equilibrium molecular dynamics (NEMD) simulations. The temperature and diameter dependence of thermal conductivity was studied in this paper. In this work, thermal conductivity of SWCNTs with the length of 24.5nm and different diameter — (6, 6), (7, 7), (8, 8), (10, 10), (15, 15) was studied...
