Magnetoresistance of vertical transport in InAs/GaSb superlattices

Abstract:

We report a study of the vertical transport of short-period InAs GaSb supertattices in high parallel magnetic fields. At low magnetic field. the current-voltage characteristic exhibits a double negative differential conductance feature. We attribute the first peak to Esaki-Tsu miniband conduction and the repeat feature to LO-phonon-assisted miniband tunnelling, At high magnetic fields, in the quantum limit we observe a series of conductance peaks that satisfy the Stark-cyclotron-resonance con...
