I.P. Studenyak

Absorption edge of Cu₆P(Si_1-xSe_x)₅I fast-ion conductors is studied in a broad temperature range. The effect of anionic substitution on the position and shape of the absorption edge as well as parameters of exciton-phonon interaction are analysed

Key words: Fast-ion conductors; ferroelastic; phase transition; absorption edge; Urbach rule; compositional disorder
