(a) Field-emission scanning electron microscopy image of graphene nanomesh. (b) Atomic structure of GNM, in which and D are the neck width and diameter of the holes, respectively. (c) The thermal conductivity κ as a function of the neck width [89]. (d) The thermal conductivity κ of GNMs as a function of the scaled density, ρ/ρ0, with circular pores arranged in hexagonal (squares), honeycomb (circles) and square (triangles) lattices [89]. Panels (a) and (b) are reproduced with permission [89, 90].
