The effect of the cross-gap alignment on magneto-transport in short period InAs/GaSb superlattices

Abstract:

We investigate de and pulsed magneto-transport in InAs/GaSb superlattices, at low temperatures. High electric and magnetic fields up to 14.5T are applied parallel to the superlattice growth direction. In the low electric and magnetic field regimes eve observe a temperature dependent threshold to conduction. At higher biases the superlattice exhibits a large magneto-resistance and in the quantum limit we observe conduction peaks, which satisfy the Stark-cyclotron-resonance condition. We have p...
