摘要

强太赫兹场增强了光激发石墨烯的太赫兹传输,增加了载流子散射率。高场打开了光载流子的空态,减少了光载流子的弛豫时间,而光激发则延缓了弛豫过程。

Ultrafast Photocarrier Dynamics in Single-Layer Graphene Driven by Strong Terahertz Pulses
Strong THz field enhances the THz transmission of photoexcited graphene, increasing carrier scattering rates. High-field also reduces the relaxation time of the photocarriers by opening up the unoccupied states, while photoexcitation retards the relaxation process.
