Abstract

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.
