| Sumario: | The metal–insulator transition of the Peierls type is studied in organic crystals of tetrathiotetracene iodide with the lowest carrier concentration value in a 2D approximation. The two most important electron–phonon interaction mechanisms—of the deformation potential type and the polaron type—are considered. The dynamical interaction of carriers with defects is also taken into account. The renormalized phonon spectrum is calculated; it is shown that the transition is of the Peierls type. |
