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…

Ultrafast changes in lattice symmetry probed by coherent phonons
Simon Wall, Daniel Wegkamp, Laura Foglia +4
The electronic and structural properties of a material are strongly determined by its symmetry. Changing the symmetry via a photoinduced phase transition offers new ways to manipul…
