摘要

在同时的光和电激励下，我们实验证明了通过石墨烯-硅混合结构对传输的太赫兹波进行主动调制。观察到83%的大传输调制。同时，在这种结构中发现了“二极管”行为，其中太赫兹波在正电压偏置时传输，而在低负电压下衰减。

Active terahertz modulations based on graphene-silicon hybrid structures

With simultaneous optical and electrical excitations, we experimentally demonstrate an active modulation of transmitted terahertz waves through a graphene-silicon hybrid structure. A large transmission modulation of 83% was observed. Meanwhile, a “diode” behavior was found in such a structure, where terahertz waves transmits when biased with a positive voltage while attenuates under a low negative voltage.
