  • Manifestation of deformation effect in band spectra in crystals with inhomogeneous bonding 
    Bercha, D.M.; Rushchanskii, K.Z.; Slipukhina, I.V.; Bercha, I.V. (Condensed Matter Physics, 2003)
    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. The first-principles ...
  • Phonon spectra of Cu₆PS₅Br superionic ferroelastic: experimental and theoretical studies 
    Studenyak, I.P.; Rushchanskii, K.Z.; Buchuk, R.Yu.; Stephanovich, V.O. (Condensed Matter Physics, 2007)
    The anomalous temperature behavior of the Raman scattering bands at superionic phase transition of Cu₆PS₅Br is revealed. Using density functional perturbation theory within local density approximation, ab initio long-wavelength ...
  • Structure similarity and lattice dynamics of InSe and In₄Se₃ crystals 
    Bercha, D.M.; Rushchanskii, K.Z.; Kharkhalis, L.Yu.; Sznajder, M. (Condensed Matter Physics, 2000)
    In the work it was shown that the In₄Se₃ crystal is similar by its dynamical properties to the InSe modulated crystal. The transformation of the D⁴₆h symmetry group of β-InSe crystal to D⁹₂h group of the In₄Se₃ structure and ...
