    • Deep SL are unsuitable for these investigations because resonant interminiband tunneling of below barrier minibands strongly masks the coupling to above-barrier states.

    • note
    • Since we study the wave function delocalization in a super-lattice, we cannot observe the catastrophic electrical Zener breakdown seen in a bulk sample: there, the transfer of a large number of carriers from the filled valence band leads to an increase of the number of mobile carriers by many orders of magnitude, whereas in a SL, only the comparatively small number of photoexcited carriers is transferred to higher minibands. In the current-voltage curves of our sample, we thus cannot observe a significant effect.

    • Linear spectra of sample B are almost identical to sample A; the main difference being a weaker coupling to the continuum in sample B due to somewhat higher barriers.

    • Because of the progressing WSL localization an excitation of a Bloch oscillating wave packet is not possible for higher fields.
