FIG. 1.

The full band structure of calculated by the LCAO method. The band folding effect generates two conduction bands ( and ), which are crossing at the saddle point.

FIG. 2.

(a) The spin-splitting energies for and bands of wurtzite , i.e., and , respectively, are plotted against for and . The anti-crossing between (solid lines) and bands (dash lines) is shown. (b) The probabilities of the density of states for and waves in the two conduction bands.

FIG. 3.

The spin-splitting energies of are plotted against the well thicknesses from one to ten layers QWs at , for the cases without electric field (open circles) and applied electric field (solid squares). The probabilities of the density of states for and waves in and are shown in the inset.

FIG. 4.

The diagram of band gap vs lattice constant. The lattice constant and energy gap of are and , respectively.
