摘要

二维钙钛矿中激子介导的超快特性是由自由载流子的量子限制引起的。与超材料集成后，在超快时间尺度(~ 20ps)下，太赫兹场的调制率达到93%。

Exciton mediated ultrafast feature of hybrid 2D perovskite THz metadevice

We show exciton mediated ultrafast feature in 2D perovskite arises due to quantum confinement of free carriers. Integrating it with metamaterials exhibit 93 % modulation of terahertz field at ultrafast time scales (~ 20 ps).
