We demonstrate a photonic metamaterial that shows extraordinary sensitivity to the presence of a single atomic layer of graphene on its surface. Metamaterial's optical transmission increases multi-fold at the resonance frequency linked to the Fano-type plasmonic mode supported by the periodic metallic nanostructure. The experiments were performed with chemical vapor deposited (CVD) graphene covering a number of size-scaled metamaterial samples with plasmonic modes at different frequencies ranging from 167 to 187 Thz.
我们展示了一种光子超材料，它对其表面单个原子层石墨烯的存在表现出非凡的敏感性。在与周期性金属纳米结构所支持的法诺型等离子体模式相关的共振频率下，超材料的光传输会成倍增加。实验是用化学气相沉积（CVD）石墨烯进行的，该石墨烯覆盖了多个尺寸缩放的超材料样品，这些样品具有从167到187太赫兹不同频率的等离子体模式。
