Analysis of exciton reflection spectrum of 2H-PbI₂ layered single crystals with atomically clean surface

Dorogan, V.G.; Zhydkov, V.O.; Motsnyi, F.V.; Smolanka, O.M. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)

We performed the computer modelling of the dispersion dependences of real ε₁(E) and imaginary ε₂(E) parts of complex dielectric function ε(E) for 2H-PbI₂ crystals with atomically clean surface at the temperature 5 K and ...
Effect of temperature variation on shift and broadening of exciton band in Cs₃Bi₂I₉ layered crystals

Machulin, V.F.; Motsnyi, F.V.; Peresh, E.Yu.; Smolanka, O.M.; Svechnikov, G.S. (Физика низких температур, 2004)

The exciton reflection spectra of Cs₃Bi₂I₉ layered crystals is investigated in the temperature region 4.2–300 K with light polarization E ⊥ c. It is estimated that the energy gap Eg equals 2.857 eV (T = 4.2 K) and the ...
Phase transition in Cs₃Bi₂I₉ ferroelastic: investigation by Raman scattering technique

Motsnyi, F.V.; Vuychik, M.V.; Smolanka, O.M.; Peresh, E.Yu. (Functional Materials, 2005)

Raman scattering in unpolarized light has been studied for the first time for Cs₃Bi₂I₉ layered ferroelastic at temperatures from 5 to 300 К in the heating mode. Neither soft mode nor frequency softening was ...
