Abstract
While ultrafast semiconductor spectroscopy has investigated scattering times, i.e. the time between different scattering events, for many years, quantum kinetics asks for the duration of one scattering process, i.e. for the memory time. For the electron-LO-phonon quantum kinetics in the weak coupling regime (GaAs), quantum kinetics shows up as an oscillation in the coherent four-wave mixing (FWM) signal. This observation was interpreted as an oscillation of a band electron back and forth between its initial and a final state it scatters into (for long times) due to the emission of n = 1 phonon.1,2
