Scattering effects from neighboring atoms in core-level WSe2 photoemission

Marcelo J. Ambrosio, Étienne Plésiat, Piero Decleva, Pedro Miguel Echenique et autres

Methods of attosecond science originally developed to investigate systems in the gas phase are currently being adapted to obtain temporal information on the electron dynamics that takes place in condensed-matter systems. In particular, streaking measurements have recently been performed to determine photoemission …

Time-resolved interferometric photoemission from Cu(111) and Ni(111) surfaces

Marcelo J. Ambrosio, Uwe Thumm

Synopsis We calculated spectra and phases for photoemission from Cu(111) and Ni(111) surfaces. Our numerical model reproduces recently measured final-state shape resonances of the photoelectron in the substrate potential.

Surface-near-field reconstruction from streaked photoelectron spectra of Au(111) surfaces

Marcelo J. Ambrosio, Uwe Thumm

Synopsis We calculate attosecond streaking traces from Au(111) surfaces and suggest their use for characterizing the plasmonic/dielectric response of solids at the nanoscale.

Spatiotemporal analysis of a final-state shape resonance in interferometric photoemission from Cu(111) surfaces

Marcelo J. Ambrosio, Uwe Thumm

Photoemission from solid targets includes the excitation and motion of electrons inside the substrate, followed by their propagation in vacuum and detection. It thus depends on the electronic band structure of the solid in the two distinct spectral domains of bound initial …
