Electron correlation effects on exciton dissociation in the presence of an electric field in polyacetylene.

Highlights: [•] The dynamics of exciton dissociation in conjugated polymers are investigated. [•] Both the effects of electron-lattice and electron-electron interactions are considered. [•] The different dynamic dissociation behaviors of SE and TE are emphasized. [•] The critical dissociation field for TE is 3 times higher than that of the SE. [•] The dissociation behaviors are analyzed by calculating the total energy difference. [ABSTRACT FROM AUTHOR]
