向导电聚合物链中添加电子或空穴已被证明会导致链扭曲，产生大的极化子。本文通过数值求解含有额外电子的聚乙炔链上电子波函数和晶格位移的耦合方程，证明了在>= V/cm的电场中极化子不形成，已经形成的极化子将被解离。将讨论的电流-电压特性的影响。
Addition of an electron or hole to a conducting polymer chain has been shown to cause the chain to distort, creating a large polaron. We show, by numerical solution of the coupled equations for the electron wavefunctions and the lattice displacements on a polyacetylene chain with an extra electron, that the polaron does not form in electric fields >= V/cm an already formed polaron will be dissociated. Implications for the current-voltage characteristic will be discussed.
