Colossal Terahertz Emission with Ultrafast Tunability Based on Van der Waals Ferroelectric NbOI<sub>2</sub> (Advanced Optical Materials 15/2025)
Colossal THz Emission with Ultrafast Phonon Tunability from vdW Ferroelectrics NbOI2 Colossal THz emission from a van der Waals (vdW) ferroelectric semiconductor NbOI2 upon optical light excitation. The long-lived phonon mediated by Nb-O atoms oscillation in the middle of the layer contribute to the THz emission and demonstrate the ultrafast coherent tunability by a double-pump scheme. More details can be found in article 2403471 by Jun Xiao and co-workers.
