Abstract

We investigate the electron-hole dynamics in few-layer InSe, a van der Waals semiconductor with promising opt-electronic properties. We show that terahertz pulses modulate the spontaneous emission via absorption by photo-excited carriers. We further study the carrier-phonon interaction in the cooling process of the hot carriers, elucidating the roles of acoustic and optical phonons.
