Localization-dependent charge separation efficiency at an organic/inorganic hybrid interface
Laura Foglia, Lea Bogner, Martin Wolf +1
By combining complementary optical techniques, photoluminescence and time-resolved excited state absorption, we achieve a comprehensive picture of the relaxation processes in the o…

Ultrafast exciton formation at the ZnO(100) surface
J. -C. Deinert, D. Wegkamp, M. Meyer +3
We study the ultrafast quasiparticle dynamics in and below the ZnO conduction band using femtosecond time-resolved two-photon photoelectron spectroscopy. Above band gap excitation…

Instantaneous band gap collapse in photoexcited monoclinic VO due to photocarrier doping
Daniel Wegkamp, Marc Herzog, Lede Xian +8
Using femtosecond time-resolved photoelectron spectroscopy we demonstrate that photoexcitation transforms monoclinic VO quasi-instantaneously into a metal. Thereby, we exclude…
