Radiative Exchange between Graphitic Nanostructures: A Microscopic Perspective

Anh D. Phan, Sheng Shen, and Lilia M. Woods

Electromagnetic radiative heat exchange involving graphene nanostrucrures is studied using an atomistic approach based on the coupled dipole method modified by the fluctuation dissipation theorem. This method includes taking into account many-particle electromagnetic contributions and enables treating two or more nanostructures with nontrivial boundary conditions at different temperatures. We present a microscopic picture of the heat exchange process in graphene nanostructured based systems in terms of a transmission coefficient, characteristic temperature function, and atomic morphology. Our studies provide general pathways of near-field radiation control at the nanoscale.
