Аннотация
Theoretical and experimental investigations of the energy-band structure and optical properties of LiRbSO4 crystals of the orthorhombic Pnma phase have been performed. The band structure, density of states, and permittivity distribution ε(E) have been calculated within the electron-density functional theory by the pseudopotential method. Spectral dependences of birefringence Δnі of LiRbSO4 crystals for different crystallophysical directions have been obtained based on these calculation results. The experimental and theoretical birefringence spectra are found to be in good agreement.
