dc.description.abstract
Femtosecond time-resolved two-photon photoemission spectroscopy is employed to
study the dynamics of an excited state in a thin regioregular
poly(3-hexylthiophene) (RR-P3HT) film deposited on a conducting polymer
poly(3,4-ethylene-dioxythiophene): poly-(styrenesulfonate) (PEDT:PSS)
electrode following optical excitation at 2.1 eV. We found that the
biexponential decay of this excited state has a fast component (2.6 ps)
assigned to bound polaron pairs which recombine quickly or separate to be
added to the slow component (7.6 ps). The latter is attributed to polarons
generated via charge transfer between adjacent polymer chains.
