Effect of disorder on exciton dissociation in conjugated polymers Project supported by the National Natural Science Foundation of China (Grant Nos. 11474218 and 11575116). |
(color online) The mean critical dissociation electric field ⟨E⟩ and the standard deviations (plotted as error bar) as a function of the degree of on-site disorder σε for different on-site Coulomb repulsion U: (a) single exciton; (b) triplet exciton. |
