摘要

金属二维Ti3C2Ty MXene在太赫兹频率范围内具有高导电性和强的电磁辐射吸收能力。我们证明了光脉冲(400nm和800nm)在MXene中诱导瞬态宽带太赫兹透明，持续纳秒，与95至290 K的温度无关。这种光控太赫兹电磁干扰屏蔽材料可用于未来的太赫兹通信系统。

A Novel THz Electromagnetic Interference Shielding Material: 2D Ti3C2Ty MXene

Metallic 2D Ti3C2Ty MXene shows high electrical conductivity and strong absorption of electromagnetic radiation in the THz frequency range. We demonstrate that optical pulses (400nm and 800nm) induce transient broadband THz transparency in this MXene, which lasts for nanoseconds and is independent of temperature from 95 to 290 K. This optically controlled THz electromagnetic interference shielding material could be exploited in future THz communication systems.
