Abstract
Cyclotron-resonance (CR) experiments have been performed on InAs/GaSb/AlSb double structures, in which electron and hole layers are separated by AlSb barriers. The strength of the electron-hole coupling is altered by varying the barrier width. Our data reveal that properties of InAs/GaSb systems wit h AlSb barriers thinner than 1.5 nm are entirely determined by interlayer t unneling and the CR features in such samples can be explained by hybridizat ion between states in the InAs conduction band and in the GaSb valence band .
