Polaron to Bipolaron Transition in Conjugated Polymers

Abstract:

Article Preview

A possible mechanism of polaron to bipolaron transition is investigated based on the well known SSH model. We have studied the dynamical process of collision between two positively charged polarons with same spin in the presence of external electric fields. It is found that when the relative velocity of collision is not very large, the collision leads to a direct transition of two polarons to a bipolaron.
