Localized excited charge carriers generate ultrafast inhomogeneous strain in the multiferroic BiFeO
D. Schick, M. Herzog, H. Wen +7
We apply ultrafast X-ray diffraction with femtosecond temporal resolution to monitor the lattice dynamics in a thin film of multiferroic BiFeO after above-bandgap photoexcitati…
Direct time domain sampling of sub-THz coherent acoustic phonon spectra in SrTiO using ultrafast X-ray diffraction
Roman Shayduk, Marc Herzog, André Bojahr +8
We synthesize sub-THz longitudinal quasi-monochromatic acoustic phonons in a SrTiO single crystal using a SrRuO/SrTiO superlattice as an optical-acoustic transducer. Th…
Following Strain-Induced Mosaicity Changes of Ferroelectric Thin Films by Ultrafast Reciprocal Space Mapping
D. Schick, A. Bojahr, M. Herzog +3
We investigate coherent phonon propagation in a thin film of ferroelectric PbZr0.2Ti0.8O3 (PZT) by ultrafast x-ray diffraction (UXRD) experiments, which are analyzed as time-resolv…
Ultrafast x-ray diffraction studies of photoexcited coherent phonons in SrRuO thin films
Daniel Schick, Peter Gaal, André Bojahr +6
We present ultrafast x-ray diffraction experiments on thin films of metallic SrRuO (SRO) after their excitation with ultrashort intense laser pulses. Depending on the layer thi…
