a Schematic of the pump–probe experiment to verify the influence of the phonon population on the carrier relaxation. b Result of the pump–probe experiment with and without the THz pulse. The broken curve shows the theoretical prediction. Adapted with permission from ref. 27, licensed under CC BY 4.0.
