Abstract
High-field magneto-resistance (MR) properties including Shubnikov de-Haas (SdH) oscillation and integer quantum Hall effect are observed and analyzed in high In-content InGaAs/InAlAs two-dimensional electron gas (2DEG) with strong Rashba effect. From the results, conventional longitudinal resistance oscillations with Zeeman splittng as well as quantum Hall plateaus are confirmed and a transition from zero-field spin-splitting to high-field Zeeman splitting is discussed. The two-kind spin splittings are seem to be connected via the sign changing process at finite (∼3 Tesla) magnetic field, the value of which is about two times larger than that in high In-content InGaSb/InAlSb system.
