应力对石墨烯热输运性质影响的分子动力学模拟
Molecular dynamics simulation of the effect of stress on the thermal transport properties of graphene
摘要
Abstract
The thermal conductivity model of low dimensional thin film materials is established in this paper, non-equilibrium molecular dynamics simulation method is used to analysis thermal conductivity characteristics of the thermal conductivity area under the action of the monolayer graphene nanoribbons stress. The reliable experi-mental data are selected. The Fourier's law is used to calculate the thermal conductivity, and the results are com-pared with the complete graphene nanoribbons. Simulation results show that:1 ) The stress applied on graphene nanoribbons will cause the thermal conductivity of graphene nanoribbons increases as the stress increases, ther-mal conductivity increased by 261% in the heat conduction simulation range. 2 ) The change of thermal conduc-tivity will be affected by the stress direction. It provides a new idea for the further improvement of thermal con-ductivity on the nanometer scale.关键词
