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…
Demonstration of a picosecond Bragg switch for hard x-rays in a synchrotron-based pump-probe experiment
M. Sander, R. Bauer, V. Kabanova +5
We report a benchmark experiment that demonstrates shortening of hard x-ray pulses in a synchrotron-based optical pump - x-ray probe experiment. The pulse shortening device, a pico…
Linear dichroic soft X-ray microscopy of ferroelectric stripe domains in epitaxial KNaNbO
M. Schneider, T. A. Butcher, S. Wagner +19
Functional properties of ferroelectric thin films are governed by domains that can be engineered by epitaxial strain. Soft X-ray microscopy can image domain structures with element…
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…
Thermoelastic study of nanolayered structures using time-resolved x-ray diffraction at high repetition rate
H. A. Navirian, D. Schick, P. Gaal +3
We investigate the thermoelastic response of a nanolayered sample composed of a metallic SrRuO3 (SRO) electrode sandwiched between a ferroelectric Pb(Zr0.2Ti0.8)O3 (PZT) film with…
Full spatiotemporal control of laser-excited periodic surface deformations
J. -E. Pudell, M. Sander, R. Bauer +3
We demonstrate full control of acoustic and thermal periodic deformations at solid surfaces down to sub-nanosecond time scales and few-micrometer length scales via independent vari…
