Abstract:
Femtosecond time-resolved two-photon photoemission spectroscopy is employed to
study the dynamics of the non-equilibrium electron distribution in the
conducting polymer poly(3,4-ethylene-dioxythiophene): poly-(styrenesulfonate)
(PEDT:PSS) film following optical excitation at 2.1 eV. We found that the
electron thermalization occurs on a ultrafast timescale of around 60 fs
analogous to the relaxation times of optically excited electrons in Au(111).
