Paper Abstract

Oscillation parameters of narrow band layered crystals of bismuth selenide and telluride and antimony telluride for one and two oscillations are calculated. The electron oscillation crystal model equations of real epsilonr and imaginary epsilonι, ω epsilonι components of dielectric function, electronic losses L, ωL are given, special points of the optical functions epsilonr, epsilonι, ω epsilonι, L, ωL for boundary frequencies ω are probed. Ratios of energy balance of `sublattices on the basis of oscillation electronic model are revealed. It is concluded that these crystals at high hydrostatic pressures and low temperatures are turned into superconductors. In high-temperature superconductors spontaneous division into two phases: superconducting and isolating was revealed. Stratification on two phases in superconducting crystals has been confirmed experimentally: neutron graphic, neutron spectral and spectral researches, an electronic and nuclear paramagnetic resonance.
