This work investigates the thermoelectric properties of a three dimensional nanofoam of few layer graphene (3D-NFG) decorated w ith holes having diameter of several tens of nanometer. The nanopor ous 3D graphene structures were fabricated by a chemical vapor deposit ion method to ensure high electrical conductivity required for pote ntial applications as thermoelectric materials. The thermal conductiv ity of the suspended 3D-NFG samples was measured by an optothermal met hod and found to be 10.8 W m(-1) K-1. The substantially reduced values of thermal conductivity were attributed to the small diameter of thepores and their inhomogeneous distribution. Suppression of heat con duction with preserved electrical conductivity is beneficial for the proposed thermoelectric applications.
