  text: The evolution of the quantum mechanical phase of electronic wave packets on
    seattering-with phonons is an issue of great relevance in solid-state physics.
    In semiconductor superlattices, evidence for phase conservation on scattering
    was obtained when time-resolved THz-emission experiments indicated that the dephasing
    of the probed intraband coherence may proceed slower than the relaxation of carriers
    via emission of LO-phonons estimated to occur on a 200-fs time scale as in bulk
    GaAs.1 To corroborate this interpretation, the unknown LO-phonon emission times
    in the superlattices must be measured for the experimental conditions of the THz-emission
    experiments. In this paper, a combined investigation of the coherent and incoherent
    dynamics of optically excited charge carriers in a superlattice structure is presented.
    A comparison of the characteristic time constants provides clear evidence for
    the conservation of the phase of the intraband coherence on LO-phonon relaxation.
