▎ 摘　　要

We propose a multilayer structure alternately stacked by graphene, silicon carbide (SiC) film, and hexagonal boron nitride (hBN) bulk to theoretically study the near-field radiative heat transfer. Compared with blackbody result, the heat transfer coefficient (HTC) can be significantly enhanced due to the effect of surface plasmons (SPs), surface phonon polaritons (SPhPs), and hyperbolic modes (HMs) supported by graphene, SiC, and hBN, respectively. HTC between the proposed structures with thin SiC can even be larger than that of graphene-covered hBN. Since SPs could be coupled both with HMs supported by the hBN and with SPhPs supported by SiC, HTC can be flexibly modulated by chemical potential of graphene. In addition, HTC of another structure which is composed with graphene, hBN film, and SiC bulk in order is also investigated in detail. The impacts of the thickness of components and vacuum gap on HTCs for both configurations are also studied. The results in this study are helpful to control near-field radiative heat transfer.
