Effect of peierls transition on the phonon spectrum in organic crystals of TTT2I3 for different values of carrier concentration

Abstract

The metal-insulator transition of Peierls type and its effect on the phonon spectrum in quasi-one-dimensional organic crystals of TTT2I3 for different values of carrier concentration is studied in 2D approximation. In the frame of the physical model, two electron-phonon interaction mechanism are taken into account. The first mechanism is of deformation potential type and the second one is of polaron type.
