Controlling the temporal coherence of thermal radiation plays an important role in energy harvesting and thermal management. Conventional approaches for thermal radiation control rely on resonances in bulk thermal emitters, which usually have a large footprint and display little tunability. In this work, we explore the possibility to control coherent thermal emission with atomically thin emitters. We show that, despite the atomic thickness, the peak emissivity of these emitters could be as high as the bulk emitters. We identify several linear scaling laws for the radiative properties of atomic-scale systems, providing a pathway for controlling thermal radiation with atomic precision.

相干热辐射的原子尺度控制

控制热辐射的时间相干性在能量收集和热管理中起着重要作用。常规的热辐射控制方法依赖于体热发射器中的共振，该共振通常具有较大的占位面积并且显示出很少的可调性。在这项工作中，我们探索了用原子薄发射器控制相干热发射的可能性。我们表明，尽管原子厚度大，但这些发射器的峰值发射率可能与体发射器一样高。我们为原子尺度系统的辐射特性确定了几种线性尺度定律，从而为控制具有原子精度的热辐射提供了一条途径。
