Magnetoresistance studies of strongly coupled superlattices
We present magnetotransport results for strongly coupled InAs/GaSb superlattices. The low effective mass of carriers in the InAs/GaSb superlattice allows the study of the transport processes at fields above the magnetophonon condition, where the cyclotron spacing homega(c) is greater than the LO pho...

| Summary: | We present magnetotransport results for strongly coupled InAs/GaSb superlattices. The low effective mass of carriers in the InAs/GaSb superlattice allows the study of the transport processes at fields above the magnetophonon condition, where the cyclotron spacing homega(c) is greater than the LO phonon energy homega(LO). Magnetotransport results display Stark Cyclotron resonance and the Magnetophonon effect. Resonant tunnelling features change dramatically above the magnetophonon condition and suggest the superlattice undergoes formation of ordered electric field domain states linked to the observation of LO phonon mediated tunnelling.
