FIG. 2.

The calculated energy band structure as a function of along the [11] direction for the active region.

Image of FIG. 3.
FIG. 3.

The calculated subband energy dispersion relations of (a) and (b) for the simple active region. The solid curves are the axial approximation results while the angle-labeled curves are the standard eight-band results.
