Abstract:

The results of an experimental study of the energy spectrum of a valence band in a HgTe quantum well of width d < 6.3 nm with normal spectrum in the presence of a strong spin-orbit splitting are reported. The analysis of the temperature, magnetic field, and gate voltage dependences of the Shubnikov-de Haas oscillations allows us to restore the energy spectrum of the two valence-band branches, which are split by the spin-orbit interaction. Comparison with a theoretical calculation shows that a six-band kP theory well describes all the experimental data in the vicinity of the top of the valence band.
