摘要：
A novel phenomenon of the 'field induced charge generation' is observed recently in the elecuoluminescent polymers. The experiments show that the photoexcitation in the electroluminescent polymers can be converted into a pair of opposite charged carriers by the electric field. Our study presents the dynamical process of the charge generation in the polymer chain by solving the time-dependent Schrodinger equation, and the evolution show's that the field-induced charge generation is an ultrafast process produced in about 10 fs.
