- Abstract
- From Shubnikov-de Haas oscillations of a two-dimensional electron gas of HgCdTe, the crossover region of the Zeeman and the Rashba effects has been found. This crossover region is attributed to the inherently large Rashba and Zeeman effects in this system. The experimental data have been successfully simulated by calculations based on a non-parabolic two-band k . p theory. Using the experimentally obtained parameters, we calculate the spin-splitting energy and the spin-expectation value and quantitatively compare the Rashba and the Zeeman effects. When the magnetic field is perpendicular to the sample plane, the spin-splitting, caused by the Rashba effect, is reduced by the development of the Landau level, thereby making the Zeeman effect a relatively more dominant mechanism in the crossover region.
