Peierls transition in quasi-one-dimensional crystals of TTF-TCNQ type in a 2D approximation.

Peierls transition in quasi-one-dimensional crystals of TTF-TCNQ type in a 2D approximation.

Peierls transition in quasi-one-dimensional organic crystals of TTF-TCNQ type is studied in a 2D physical model of the crystal. The two most important electron-phonon interactions are simultaneously considered. The analytic expression for the phonon polarization operator is obtained in the random ph...
