Warping; bulk dispersion; InSb

We calculate the warping of the bulk dispersion of InSb in thek-space using different models for the bulk band structure near the Γ point. It is shown that the dispersion of the conduction band Γ₆ is well described by the simplified six-band model, while the fourteen-band model is more accurate for the valence bands.
