Modeling Many-body Effects in Ge Using Pump-Probe Femtosecond Ellipsometry
Original language description
We investigate the transient dielectric function of germanium at very high electron-hole pair densities using time-resolved spectroscopic ellipsometry. By employing a pump-probe technique, we examine how the parameters of the critical points near the L-valley evolve with delay time. Our analysis aims to develop a model describing the behavior of the material under varying carrier concentrations, with particular attention to phase-filling singularities. We leverage high-power laser-induced carriers in undoped samples to explore many-body effects and relaxation processes.
