A thermal repeater is a device that can help the heat propagate farther, acting as a relay. In this letter, we have demonstrated the possibility to efficiently relay the radiative heat flux between two nanoparticles by opening a smooth channel for heat transfer based on coupled localized-surface plasmon polaritons of graphene. By coating the nanoparticles and the substrate with a graphene shell and a graphene sheet respectively, the localized plasmon polaritons excited near the nanoparticles can couple with the surface plasmon polaritons of graphene sheet on substrate to form a smooth channel for heat transfer. The heat transfer can be enhanced by more than two orders of magnitude in the far-field regime without any additional source of energy, and the work may provide a new way to realize the energy modulation or thermal communications especially in long distance.

基于石墨烯的热中继器

热中继器是一种可以帮助热量传播得更远的设备,充当继电器。在这封信中,我们证明了通过基于石墨烯的耦合局部表面等离子体激元打开一个光滑的传热通道来有效地传递两个纳米粒子之间的辐射热通量的可能性。通过分别用石墨烯壳和石墨烯片涂覆纳米颗粒和基板,在纳米颗粒附近激发的局域等离子体激元可以与基板上石墨烯片的表面等离子体激元耦合,形成光滑的传热通道。在没有任何额外能源的情况下,远场区域的传热可以提高两个数量级以上,
