Paper Abstract

For the first time on the experimental IR reflection spectra R(λ) of α -Ag2Se films with charge carrier concentration 4,0 x 1018 cm-3 at 300 K behind of plasma minimum (1150 cm-1) are detected two further minimums (800 cm-1 and 550cm-1), stipulated by interaction of plasmon and long-wave optical (LO) phonons. It was founded the peculiarities in the behaviour of the optical function (ε1; ε2; -Im ε-1) at the interaction of the free charge carrier with the polarizable ions of lattice oscillations. The frequency of longitudinal and transversal phonons is calculated.
