摘要：Nanostructures have exhibited unprecedented optical and thermal properties including super-Planckian thermal radiation. Nevertheless, nanostructures are usually made of isotropic materials while anisotropic counterparts are rarely considered despite their wide applications. This paper investigates near-field thermal radiation between gratings consisting of natural anisotropic graphite. Graphite gratings with optical axes lying out of plane are found to possess sevenfold larger radiative heat flux than counterpart plane plates at nanoscale gap distances, outperforming blackbodies by over four orders of magnitude. The dominant radiative heat transfer channel changes from nonresonant hyperbolic modes to anisotropic surface resonant modes after patterning. The strong coupling of anisotropic surface modes with high k waves in a broad frequency range results in the extremely efficient radiative heat transfer of graphite gratings. This work helps deepen the understanding of thermal radiation of anisotropic nanostructures and opens routes for more efficient thermal radiative transport.
