4. Conclusions
The present study is focused primarily upon the thermal transport characteristics of graphene nanoribbons. The thermal transport characteristics of graphene nanoribbons are studied using molecular dynamics simulations and by experimental measurements. A specific heat flux is imposed through the graphene nanoribbon. The graphene nanoribbon is considered as a single layer of carbon atoms with each atom bound to three neighbors in a honeycomb structure. The thermal conductivity is determined from the temperature gradient obtained and the heat flux imposed. The thermal properties of the graphene nanoribbon with different lengths are investigated to determine the structure factors limiting the heat transfer process. The present study aims to provide a fundamental understanding of the thermal transport properties of graphene nanoribbons. Particular emphasis is placed upon the effect of various factors on the thermal conductivity of graphene nanoribbons under different conditions. The major conclusions are summarized as follows:
