Abstract

We report an experimental study of high electric field magnetoconduction in semiconducting InAs GaSb superlattices. This demonstrates that total quantization of the electronic states leads to conduction dominated by a combination of interwell and intrawell processes. The strongest conduction occurs for the triple Stark magnetophonon resonance where resonant interwell tunnelling coincides with (multiple) intrawell longitudinal optical phonon emission.
