论文摘要
研究了基于石墨烯 - 质量 - 材料 - 材料纳米力学系统（NEMS）的紫外线（UV）电声调制系统。由于紫外线区域中石墨烯的强光吸收强度以及基于表面等离子体的超材料结构的组合，因此与可见光区域中对应器调制器相比，UV NEMS电气调节器的调节深度接近了8.5倍。同时，由于其极低的摩擦系数，高级润滑性大大降低了紫外线电气调制系统的功耗。它还显着提高了调制器的响应速度，该响应速度可以达到纳秒级的阶。调制电压可以低于200 mV。拟议的电磁调制系统具有简单的结构和高灵敏度，该系统应该在UV光电设备和系统中具有重要的应用。
Ultraviolet (UV) electro-optic modulation system based on graphene-plasmonic metamaterials nanomechanical system (NEMS) with superlubricity is investigated. Due to the strong optical absorption intensity of graphene in the UV region and the combination of metamaterial structure based on surface plasmons, the modulation depth of the UV NEMS electro-optic modulator approaches as high as 8.5 times compared to the counterpart modulator in visible light region. Meanwhile, the superlubricity significantly reduces the power consumption of the UV electro-optic modulation system due to its extremely low friction coefficient. It also significantly improves the response speed of the modulator, which can reach the order of a nanosecond. The modulation voltage can be lower than 200 mV. The proposed electro-optic modulation system has a simple structure and high sensitivity, which is supposed to have important applications in UV optoelectronic devices and systems.
