我们研究了一种混合石墨烯等离子体装置，该装置由金纳米带阵列与石墨烯相结合组成。我们测量了纳米带阵列顶部转移单层或双层石墨烯后光学特性的显着变化。我们认为这种修改部分是由于通过石墨烯层的高移动电子进行的局域等离子体共振的电阻耦合。我们的结果为设计有源光学元件开辟了新的可能性，以利用石墨烯载流子密度对偏置电压的高灵敏度来实现超快光调制。这是特别有趣的，因为金属纳米结构的等离激元共振可以存在于可见光、近红外光和紫外光中；许多应用的重要领域。
We study a hybrid graphene plasmonic device that consists of a gold nanostripe array combined with graphene. We have measured significant changes in the optical properties of the nanostripe array after the transfer of monolayer or bilayer graphene on the top of it. We suggest that this modification is partly due to the resistive coupling of localized plasmon resonances through the highly mobile electrons of the graphene layer. Our results open up new possibilities for designing active optical elements to exploit the high sensitivity of graphene carrier-density to bias voltage for ultra-fast light modulation. This is especially interesting as the plasmonic resonances of metal nanostructures can lie in the visible, NIR and UV; important areas for many applications.
