X-ray Free Electron Laser Studies of Electron and Phonon Dynamics of Graphene Adsorbed on Copper
Hirohito Ogasawara, Han Wang, Jörgen Gladh +23
We report optical pumping and X-ray absorption spectroscopy experiments at the PAL free electron laser that directly probe the electron dynamics of a graphene monolayer adsorbed on…
Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
Universal phase dynamics in VO2 switches revealed by ultrafast operando diffraction
Aditya Sood, Xiaozhe Shen, Yin Shi +9
Strongly correlated materials that exhibit an insulator-metal transition are key candidates in the search for new computing platforms. Understanding the pathways and timescales und…
Dynamic lattice distortions driven by surface trapping in semiconductor nanocrystals
Burak Guzelturk, Benjamin L. Cotts, Dipti Jasrasaria +26
Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxation…
Terahertz-based attosecond metrology of relativistic electron beams
R. K. Li, M. C. Hoffmann, E. A. Nanni +9
Photons, electrons, and their interplay are at the heart of photonic devices and modern instruments for ultrafast science [1-10]. Nowadays, electron beams of the highest intensity…
Phonons in ultrathin oxide films - 2D to 3D transition in FeO on Pt(111)
N. Spiridis, M. Zając, P. Piekarz +10
The structural and magnetic properties of ultrathin FeO(111) films on Pt(111) with thicknesses from 1 to 16 monolayers (ML) were studied using the nuclear inelastic scattering (NIS…
Growth and electronic and magnetic structure of iron oxide films on Pt(111)
N. Spiridis, D. Wilgocka-Ślȩzak, K. Freindl +6
Ultrathin (111)-oriented polar iron oxide films were grown on a Pt(111) single crystal either by the reactive deposition of iron or oxidation of metallic iron monolayers. These fil…
