POLARONS IN CONJUGATED POLYMERS UNDER HIGH ELECTRIC-FIELDS

The static and dynamic properties of large polarons on conjugated chai ns have been calculated under high electric fields. We have found that the nonlinear self-trapping energy is not changed significantly, even at fields which confer to the polaron a potential energy larger than the formation energy in the absence of fields. However, the drift mobi lity of the polarons in an assembly of disordered conjugated segments is increased by several orders of magnitude.
