Photoinduced Domain Pattern Transformation in Ferroelectric/Dielectric Superlattices
Youngjun Ahn, Joonkyu Park, Anastasios Pateras +7
The nanodomain pattern in ferroelectric/dielectric superlattices transforms to a uniform polarization state under above-bandgap optical excitation. X-ray scattering reveals a disap…
Nanosecond Phase Transition Dynamics in Compressively Strained Epitaxial BiFeO3
Margaret P. Cosgriff, Pice Chen, Sung Su Lee +11
A highly strained BiFeO3 (BFO) thin film is transformed between phases with distinct structures and properties by nanosecond-duration applied electric field pulses. Time-resolved s…
Giant optical enhancement of strain gradient in ferroelectric thin films and its physics origin
Yuelin Li, Carolina Adamo, Pice Chen +9
The coupling between strain gradients and polarization, known as flexoelectricity, offers a new mechanism to control the functionality of dielectric materials. However, for the eff…
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…
