polarons

in our model, ferromagnetic metal electrodes are replaced by two magnetic impurities, the spin of polarons polarized at both sides while polarons with different charge and antiparallel spin recombine in the middle region of impurities.

利用两个磁性杂质取代铁磁金属电极，使聚合物两端实现极化子的自旋极化，并在两个磁性杂质中间区域得到自旋反平行的正、负电极化子的复合。

The ratio of electron spin energy to the interaction energy between electron and LO ( longitudinal optical) phonon decreases with increasing z, so does the ratio of electron spin energy to the interaction energy between polarons.

电子自旋能量与电子和LO（体纵光学）声子之间的相互作用能之比以及与声子之间的相互作用能之比都随z增加而减小。

Photoexcitation of excitons and polarons in three forms of polyaniline have been measured by using femtosecond time-resolved absorption spectroscopy technology.
