Abstract
We investigate dc miniband transport in undoped GaAs/AlxGa1−xAs superlattices. High magnetic fields are applied to the samples in the growth direction at low temperature. A strong suppression of miniband conduction is observed under these conditions. We propose a qualitative semi-classical Drude model that can explain the observed results.
