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.
