Abstract
We report an experimental study of miniband magnetoconduction in semiconducting InAs GaSb superlattices. For samples with miniband widths below the longitudinal optical phonon energy we identify a superlattice magnetophonon resonance caused by resonant scattering of electrons across the mini-Brillouin zone. This resonant feature arises directly from the superlattice dispersion and total magnetic quantization (energetic decoupling) of the superlattice Landau level minibands.
