โœฆ Synopsis

DC miniband transport is studied in undoped GaAs/AIXGal_,As 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.

Miniband transport in semiconductor superlattices in high electric and magnetic fields aligned parallel to the symmetry axis is studied within a quantum-kinetic approach that accounts for intra-collisional field effects of both fields and the heating of the lateral electron motion. Scattering on aco
