Abstract
We investigate the influence of scattering and coherent plasmon coupling on the temporal and spatial dynamics of Bloch-oscillating electrons in a semiconductor superlattice. We demonstrate that the dynamics are strongly influenced due to the scattering processes. For higher carrier densities, coupling to coherent plasmons leads to anharmonic Bloch oscillations since the static bias field is considerably changed by the oscillating carriers.
