Analysis of temperature-dependent and time-resolved ellipsometry spectra of Ge

The dielectric function of Ge measured with static and time-resolved spectroscopic ellipsometry is analyzed using linear filtering techniques to investigate the temperature dependence of the direct band gap, as well as the temporal evolvement of critical points obtained from femtosecond pumpprobe el...
