Graphene-enabled control of phonon polaritonic near-field radiative heat transfer in a CaCO 3 nanogap cavity
Abstract
plates, we implement a twistronics-inspired strategy to tailor the dispersion and coupling strength of the hybrid modes. Jointly optimizing the twist angle and graphene electron density yields an overall modulation ratio approaching 8.04. These results provide a viable route toward compact, actively tunable thermal management devices based on graphene and anisotropic phonon-polaritonic media.
