Dynamical process of photoinduced polarization reversion in polymers

In polymeric molecules, the self-trapping associated with the photoinduced polarization reversion (PPR) produces bond distortion and creates gap states. The relaxation processes of the bond distortion and the gap states are revealed by studying the dynamics of the photoexcitation. The switching spee...

Description
Summary:In polymeric molecules, the self-trapping associated with the photoinduced polarization reversion (PPR) produces bond distortion and creates gap states. The relaxation processes of the bond distortion and the gap states are revealed by studying the dynamics of the photoexcitation. The switching speed associated with the PPR can be determined from the relaxation process.
