摘要

利用室温下门控石墨烯的太赫兹泵浦/太赫兹探针光谱研究了石墨烯的太赫兹非线性及其时间动力学与自由载流子浓度的关系。强太赫兹非线性归因于驱动太赫兹场的电子加热，并表现出对背景电子浓度的强烈依赖，表明石墨烯的太赫兹非线性具有大范围可调性。

Control of Terahertz Nonlinearity in Graphene by Gating

We study the dependence of the terahertz (THz) nonlinearity of graphene and its temporal dynamics on the free carrier concentration by THz-pump/THz-probe spectroscopy of a gated graphene at room temperature. The strong THz nonlinearity is attributed to electron heating by the driving THz field and shows a drastic dependence on the background electron concentration, demonstrating a wide-range tunability of the THz nonlinearity of graphene.
