Abstract: We investigate theoretically the Rashba spin-orbit interaction in InAs-GaSbquantum wellsQWs. We find that the Rashba spin-splitting RSS dependssensitively on the thickness of the InAs layer. The RSS exhibits nonlinearbehavior for narrow InAs-GaSb QWs and the oscillating feature for wideInAs-GaSb QWs. The nonlinear and oscillating behaviors arise from the weakenedand enhanced interband coupling. The RSS also show asymmetric features respectto the direction of the external electric field.
