Colossal THz Emission with Ultrafast Phonon Tunability from vdW Ferroelectrics NbOI 2 Colossal THz emission from a van der Waals (vdW) ferroelectric semiconductor NbOI 2 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.
