Abstract

We investigate miniband conduction in GaAs/AlxGa1−xAs superlattices at low temperatures and at high magnetic fields up to 23 T. The fields are applied perpendicular to the tunnel barriers. The current flowing through the sample is strongly suppressed by the magnetic field over the voltage range corresponding to the miniband conduction peak. This effect is related to the formation of quasi-one-dimensional Landau level minibands when the cyclotron energy exceeds the miniband width.
