论文摘要
扭曲的双层石墨烯(TBG)中层间相互作用的存在增强了几种特征,包括光学和电性能。从理论上讲,我们根据费米速度消失,研究TBG的魔力角度,并在系列中找到双重魔法角度。从TBG的热辐射可以通过更改扭曲角度调节到远红外范围。奇特的辐射光谱不在大气窗口之外,这在隐形性和保持温暖中可以很好地利用。 TBG的总辐射略高于单层石墨烯的两倍。
The presence of interlayer interactions in twisted bilayer graphene (TBG) enhances several characteristics, including the optical and electrical properties. We theoretically investigate the magic angle of TBG according to the vanishing of Fermi velocity and find double magic angles in a series. The thermal radiation from TBG can be tuned to the far infrared range by changing twist angles. The peculiar radiation spectrum is out of atmospheric window, which can be of great use in invisibility and keeping warm. The total radiation of TBG is slightly more than twice of a single layer graphene.
