摘要：
DC miniband transport is studied in undoped GaAs/AlxGa1-xAs superlattices at low temperatures and at high magnetic fields applied perpendicular to the tunnel barriers. A strong suppression of miniband conduction is observed under these conditions. We propose a qualitative semi-classical Drude model to explain the observed results.
