Effect of the 2D phonon spectrum on the electric conductivity and thermopower of tetrathiotetracene iodide crystals

Thermoelectric transport along the molecular chains of quasi-one-dimensional organic crystals of tetrathiotetracene iodide, TTT2I3, is studied in terms of a quasi-two dimensional (2D) model applying the linearized Boltzmann kinetic equation. Earlier, for simplicity, we have considered the lattice vi...
