Abstract

On a femtosecond timescale, we observe how Coulomb screening and collective scattering build up in an extreme nonequilibrium electron–hole plasma photoinjected in GaAs. To this end, we generate a plasma within 10 fs and probe the subsequent polarization response of the system with uncertainty-limited temporal resolution via ultrabroadband THz spectroscopy. We show that the intrinsic material ...
