Spin–Orbit and Crystal Field Splittings of the Valence Band in II3V2 Semiconducting Compounds

The pseudopotential method is used to calculate the spin–orbit and crystal field splittings of tetragonal II3V2 compounds at the Γ point of the Brillouin Zone. The computed splittings are compared to experimental data of other authors. The resulting structure of the valence bands in these compounds at the Γ point is presented.
