Heat Transport Properties of Stable Carbon Honeycomb Structures
In recent years,carbon honeycomb structures synthesized by experiments have been widely concerned by the scientific community because of their high mechanical strength,high ther-mal conductivity and light weight.In this work,we investigate the heat transport properties of a recently proposed stable carbon honeycomb structure(hC28)using non-equilibrium molecular dy-namics methods.The results show that the thermal conductivity along the honeycomb axis is much higher than that perpendicular to the honeycomb axis,showing anisotropy.In addition,with the increase of temperature,the scattering between higher order phonons is enhanced,and the thermal conductivity of the model decreases gradually.The research results of this paper have a certain guiding significance for the development of carbon honeycomb structure as a heat conduction device.
