Abstract

Interchain hopping of solitons and polarons in polyacetylene is studied by numerical simulations of their motion under the electric field. The used model is the Su-Schrieffer-Heeger model supplemented with the intrachain electron-electron interaction and dopant potential. We find that charged solitons can hop to the opposite chain by forming a pair (bipolaron). For the case of polarons also hopping in a pair is more favorable than single polaron hopping. Interchain hopping of a polaron pair is more effective than that of a soliton pair.
