Polaron Dynamics in Impurity-doped Conjugated Polymers

摘要

Transport process of a charged polaron in impurity-doped conjugated polymers is investigated by using a nonadiabatic evolution method. Effect of the impurity ion on the polaron motion in a system of two-chains is focused. It is found that an impurity ion acts as a barrier or well rather than a bridge, which is not favourable for the polaron transport between chains.
