我们建议使用石墨烯覆盖的碳化硅（SiC）纳米线阵列（NWA）进行近场辐射传热的理论研究。 SiC NWA 在适当选择的填充体积分数下表现出双曲特性。石墨烯支持的表面等离子体和SiC NWA 支持的双曲模式显着影响辐射传热。所提出的结构之间的传热系数 (HTC) 大于 SiC NWA 之间的传热系数 (HTC)。我们还发现石墨烯的化学势在调节 HTC 方面发挥着重要作用。通过栅极电压调节化学势，可以使用石墨烯覆盖的 SiC NWA 灵活控制传热。
We propose the use of graphene-covered silicon carbide (SiC) nanowire arrays (NWAs) for theoretical studies of near-field radiative heat transfer. The SiC NWAs exhibit a hyperbolic characteristic at an appropriately selected filling-volume fraction. The surface plasmon supported by graphene and the hyperbolic modes supported by SiC NWAs significantly affect radiative heat transfer. The heat-transfer coefficient (HTC) between the proposed structures is larger than that between SiC NWAs. We also find that the chemical potential of graphene plays an important role in modulating the HTC. The tunability of chemical potential through gate voltage enables flexible control of heat transfer using the graphene-covered SiC NWAs.
