Abstract

We have investigated the properties of InAs/AlSb/GaSb electron-hole proximity systems while focusing on the influence of the AlSb barrier between the two quantum wells. We have seen that for thin AlSb barriers there is a drop in mobility due to scattering of electrons by holes. We have also observed a series of secondary absorption peaks in cyclotron resonance spectra that are caused by interband Landau-level transitions.
