The thermal conductivity (TC) of isolated graphene with different concentrations of isotope (C13) is studied with equilibrium molecular dynamics method at 300 K. In the limit of pure C12or C13graphene, TC of graphene in zigzag and armchair directions are ~630 W/mK and ~1000W/mK, respectively. We find that the TC of graphene can be maximally reduced by ~80%, in both armchair and zigzag directions, when a random distribution of C12and C13is assumed at different doping concentrations. Therefore, our simulation results suggest an effective way to tune the TC of graphene without changing its atomic and electronic structure, thus yielding a promising application for nanoelectronics and thermoelectricity of graphene-based nano device.

The molecular dynamics method was used to analyze the dynamic characteristics of water clusters in the solid and liquid phase. A criterion is proposed for choosing the interaction potential, which is based on the distributions of the potential energy of cluster molecules in different phases. The connection of the obtained distributions with the dynamics and structure of the hydrogen bonds’ net of the cluster is shown.
