| Abstract: | We investigated double-doped InGaAs/InAlAs heterostructures with high indium compositions. The heterostructures were grown by molecular beam epitaxy on GaAs(001) with metamorphic step-graded buffer layers. The magneto-transport characterization was performed by using Hall-bar devices. We observed non-monotonic magnetoresistanceoscillations, which indicate a single two-dimensional electron gas (2DEG) with multiple-subband occupationor a 2DEG bilayer. We also observed weak-antilocalization in all samples, which is an evidence of spin-orbit coupling. |
