説明

The valance band structure of tellurium near the corner of the Brillouin zone is derived, with the use of the group theory and the k·p perturbation method. The main features of the obtained valence band are the existence of the kz-linear term and of the trigonal warping about the kz axis. Because of the kz-linear term Skz, the uppermost valence band has a double maximum or a single maximum, depending on the ratio of S2⁄4B|Δ1| larger or smaller than one, where Δ1 and B are the spin-orbit interaction and band parameters, respectively. The present theory is also applicable to selenium.
