dc.description.abstract | We report the experimental results of the subnanosecond time-resolved transient photoconductivity (PC) of solid C60 film at various photon energies, and the spectral response of the steady-state PC in the energy range between 1.5 and 4.5 eV. The initial fast transient PC response decays exponentially in the subnanosecond time regime, followed by a weak slower component. Decay time at ħω=2.0 eV is longer than that at ħω=2.6 and 2.9 eV. At ħω=2.0 eV, transient PC peak shows a superlinear intensity dependence, suggesting carrier generation via exciton-exciton collision ionization, consistent with the recent results of fast photoinduced absorption. However, the linear intensity dependence of the transient PC at ħω=2.6 and 2.9 eV and a sharp increase of the transient and steady-state PC response at ħω≊2.3 eV indicate direct photogeneration of free electrons and holes at ħω>2.3 eV. | en |
