Interchain tunnelling of large polarons and bipolarons in quasi-1D solids

Abstract

The formation of interchain bands for continual polarons and bipolarons in quasi-1D conducting polymers and molecular systems is considered at zero temperature. For the case of nonadiabatic tperpendicular to hopping, a qualitatively strong dependence is found of the interchain tunnelling of polarons/bipolarons on their intrachain motion and on the type of 3D ordering. Relevant experiments are proposed.
