摘要：
In conducting polymers, a polaron carries charge +/-e with spin s = +/-1/2, and a bipolaron carries charge +/-2e without spin. Hence, the polaron is a spin carrier but the bipolaron is not. Through a dynamical simulation, our study of photoinduced phenomena shows that, by absorbing a photon, a bipolaron is split into two polarons. This photoinduced splitting converts a charge carrier (bipolaron) into two spin carriers (polarons). (C) 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
