Femtosecond concerted rotation of molecules on a 2D material interface
Kiana Baumgärtner, Misa Nozaki, Marvin Reuner +20
Interfaces between molecules and 2D materials exhibit energy-driven functionalities, wherein charge transfer directs molecular motion. Unlike equilibrium systems, where molecular a…
Propagating charge carrier plasmon in Sr2RuO4
Martin Knupfer, Fabian Jerzembeck, Naoki Kikugawa +2
We report on studies of charge carrier plasmon excitations in Sr2RuO4 by transmission Electron Energy-Loss Spectroscopy. In particular, we present results on the plasmon dispersion…
Multispectral time-resolved energy-momentum microscopy using high-harmonic extreme ultraviolet radiation
Michael Heber, Nils Wind, Dmytro Kutnyakhov +5
A 790-nm-driven high-harmonic generation source with a repetition rate of 6 kHz is combined with a toroidal-grating monochromator and a high-detection-efficiency photoelectron time…
Lifetime of quasi-particles in the nearly-free electron metal Sodium
D. V. Potorochin, R. Kurleto, O. J. Clark +8
We report a high-resolution angle-resolved photoemission (ARPES) study of the prototypical nearly-free-electron metal sodium. The observed mass enhancement is slightly smaller than…
Direct observation of charge separation in an organic light harvesting system by femtosecond time-resolved XPS
Friedrich Roth, Mario Borgwardt, Lukas Wenthaus +8
The ultrafast dynamics of photon-to-charge conversion in an organic light harvesting system is studied by femtosecond time-resolved X-ray photoemission spectroscopy (TR-XPS) at the…
Evidence for an orbital dependent Mott transition in the ladders of (La,Ca)SrCuO derived by electron energy-loss spectroscopy
Friedrich Roth, Alexandre Revcolevschi, Bernd Büchner +2
The knowledge of the charge carrier distribution among the different orbitals of Cu and O is a precondition for the understanding of the physical properties of various Cu-O framewo…
