Nonlinear soliton transport in charge transfer compounds

Nonlinear conductivities and anomalous current switching effect have been widely observed in single crystals of semiconducting organic charge transfer compounds. These features are found to be strongly dependent on the molecular ionicity and the stack structures, indicating that the switching effect is attributed to the breakdown of bond-ordered-wave (BOW) state induced by soliton current.

Electrical Switching Effect in Organic Charge Transfer Compounds

Abstract A current switching effect in charge transfer compounds has been investigated by probing photoconductivity. It has been found that the life time of photocurrent is suddenly elongated when the crystal is switched to the on-state of current.

Switching effect in organic charge transfer complex crystals

A reproducible current switching effect has been observed in various mixed-stack organic charge transfer crystals whose ionicities are close to the neutral-ionic phase boundary. This effect appears to be related to the intrinsic nonlinear conductivity, which has recently been reported in these crystals. This switching has a reasonably large delay time and our results indicate that it is a bulk property of the crystals. Discussion is given on the possible mechanism of this effect.
