Manifestation of deformation effect in band spectra in crystals with inhomogeneous bonding
The effect of the shear strains on the energy spectrum of the strongly anisotropic SbSI crystal has been investigated by group-theoretical method in combination with the Pikus method of invariants.

anisotropic SbSI crystal has been investigated by group-theoretical method
in combination with the Pikus method of invariants. The first-principles local
density approximation has been implemented to determine the band structure
of the crystal. Ab initio calculations of the band structure have shown
an exact localization of twofold degenerate maximum of the valence band
in the T point. It turned out that the shear strains result in the band topology
changes in the vicinity of the T point and the k -linear term appears in the
corresponding dispersion law. |
