Linear optical spectroscopy shows that, for high fields, the well-known localization of the Bloch states is followed by a field-induced delocalization, associated with Zener breakdown. Using time-resolved measurements, we observe Bloch oscillations in a regime where they are damped by Zener breakdown.enIII-V semiconductorIII-V HalbleitersuperlatticeÜbergitteroptical measurementoptische Messungtimeresolved measurementzeitaufgelöste Messung621667530journal article
