摘要

Near-field thermal transfer between material bodies is generally obtained by numerical calculation methods. We present simple close-form analytic results for heat transfer between planar structures, derived by explicitly relating the heat transfer to the dispersion relations of the coupled systems. In the conventional case of heat transfer between SiC slabs, the closed-form analytic results agree excellently with numerical simulations. In the case where two graphene sheets are separated by a distance d, our theory shows that the heat transfer scales as 1/d, rather than 1/d(2) as in the conventional cases, due to the unique dispersion relation of two-dimensional plasmons.
