Using molecular-dynamics simulations, we study the thermal transport properties of graphene nanomeshes (GNMs) as a function of material density, pore morphology, pore edge passivation, and the lattice arrangement of the nanomesh pores. Relations for the density dependence of the GNMs' thermal conductivity are established. For GNMs with circular pores, we find that the thermal conductivity is an exponential function of the GNM's neck width with a very weak dependence on the pore lattice structure and pore edge passivation. For GNMs with elliptical pores, the thermal conductivity becomes anisotropic and this anisotropy becomes stronger with decreasing GNM density. (C) 2014 AIP Publishing LLC.
