Drift velocity for acoustic polarons in 1D conductors
Gogolin A. A.
The drift velocity v0(E) is calculated for an acoustic polaron with strong coupling in a ID polymer chain. The limiting cases of low and high temperatures are analyzed. The functional dependence v0(E) exhibits a characteristic saturation in strong fields near the sound velocity s. This behavior of the drift velocity was recently observed in polydiacetylene, PDA [K. J. Donovan and E. G. Wilson, J. Phys. С 18, L51 (1985); Philos. Mag. B44, 9, 31 (1981)].
