  • The band energy structure of RbKSO₄ crystals 
    Bovgyra, O.V.; Stadnyk, V.Yo.; Franiv, A.V.; Tuzyak, M.R.; Chyzh, O.Z. (Condensed Matter Physics, 2007)
    The energy band structure of mechanically free and compressed RbKSO₄ single crystals is investigated. It is established that the top of the valence band is located at the D point of the Brillouin zone [k = (0.5, 0.5, 0)], ...
  • The baric changes of the refractive properties of K₂SO₄ crystals 
    Stadnyk, V.Yo.; Romanyuk, M.O.; Chyzh, O.Z.; Vachulovych, V.F. (Condensed Matter Physics, 2007)
    The dependencies of the birefringence ∆ni of K₂SO₄ crystals in wide spectral (250–800 nm) ranges, as well as the effect of uniaxial mechanical stress on them have been studied. The values of ni for K₂SO₄ are found to be ...
  • The refractometry of the uniaxially stressed ferroelectrics 
    Romanyuk, M.O.; Stadnyk, V.Yo. (Condensed Matter Physics, 1999)
    The effect of uniaxial mechanical stresses upon the spectral and temperature dependences of birefringences in some ferroelectric crystals with the incommensurate phase are studied. Considerable baric displacements of ...
