Abstract :
Ultrafast dynamics of photo-excited electrons with non-equilibrium distribution in GaAs has been studied on femtosecond time scale, by means of energy- and angle-resolved two-photon photoelectron spectroscopy. Fundamental scattering processes governing their energy relaxation are elucidated.
