Abstract

The Rashba spin–orbit splitting of 2D electron gas in gated HgCdTe surface quantum wells on nn-HgCdTe is studied experimentally (by the magneto-capacitance spectroscopy of Landau level method) and theoretically with emphasis on the peculiarities of spectrum at surface densities NsNs corresponding to the onset of 2D subbands occupancy, where the regime of kinetic binding is realized. Although the spin–orbit splitting in kinetic confinement regime is small, the “Rashba polarization” Δn/nΔn/n can achieve 100% because of strong difference in values of cutoff wave vector kckc for different spin-split sub-subbands.
