It is observed from the theoretical investigation that GNR has highly length and width dependent thermal conductivities due to difference in the in/out-plane phonon mode in the phonon dispersion curve (PDC). The calculations show that thermal conduction of graphene nanoribbon increases with increasing edge roughness of graphene nanoribbons. Our findings are helpful for understanding and engineering of the thermal conductivity of graphene nanoribbons in potential electronic devices.
