论文摘要
在这封信中,通过一种涂层方法实现了两种各向同性材料之间近场辐射传热(NFRHT)的主动控制。这两个平板涂有石墨烯光栅,然后通过调整两个光栅之间的扭曲角度,不仅可以增强NFRHT,而且可以减弱。物理机制归因于石墨烯光栅和各向同性材料的模式,它们可以随扭曲的角度变化。所提出的方法还适用于其他各种各向异性膜,并且可以提供一种实现高精度纳米级热管理,灵活的热通信和热开关的方法。
In this letter, active control of near-field radiative heat transfer (NFRHT) between two isotropic materials is realized by a coating-twisting method. The two slabs are coated with graphene gratings, and then the NFRHT can be not only enhanced, but also weakened, by tuning the twisted angle between the two gratings. The physical mechanism is attributed to the modes coupled by the graphene gratings and the isotropic material, which can vary with the twisted angle. The proposed method is also applicable for other kinds of anisotropic films, and may provide a way to realize high-precision nanoscale thermal management, nimble thermal communications and thermal switch.
