中文摘要：

本文研究了微纳尺度下金属平行平板间辐射换热的问题,说明了微纳尺度下的近场效应使得结构间的辐射换热得到了极大的增强,并大大超过了黑体辐射的理论极限。并通过在结构中引入石墨烯层,研究了石墨烯对金属平行平板结构近场辐射的调控作用。结果表明,与电介质材料的增强效果不同,石墨烯层的引入有效的抑制了新结构中的近场效应。和结构的特征尺寸相比,单层石墨烯具有非常小的厚度,因此可以认为石墨烯具有非常好的热调控前景。

英文摘要：

The authors study the radiative heat transfer between double-layer plates at micro/nano scale, demonstrating the significant enhancement of the radiation flux caused by the near-field effects, which is much larger than the blackbody radiation limit. Then the authors attach the graphene layer to the metal plate and calculate the radiation flux between the new structure. It is found that the near-field effects are suppressed in the new structure, which is different from some other materials. Compared with the feature size of the structure, the thickness of graphene layer is very small, so graphene is considered having a broad prospect in thermal applications.
