Figure 1: Band structure of InAs0.92Bi0.08 in the vicinity of the Brillouin zone center (Γ-point). Shown are the lowest conduction band (energetically highest band shown), the heavy-hole band (band in the middle) and the light-hole band (energetically lowest band shown). The gap between the heavy-hole and the light-hole band at the Γ-point corresponds to the observed valence band splitting (VBS).
