Photostrictive actuators based on freestanding ferroelectric membranes
Saptam Ganguly, David Pesquera, Daniel Moreno Garcia +9
Complex oxides offer a wide range of functional properties, and recent advances in fabrication of freestanding membranes of these oxides are adding new mechanical degrees of freedo…
Translational boundaries as incipient ferrielectric domains in antiferroelectric PbZrO3
Ying Liu, Ranming Niu, Andrzej Majchrowski +4
In the archetypal antiferroelectric PbZrO3, antiparallel electric dipoles cancel each other, resulting in zero spontaneous polarisation at the macroscopic level. Yet in actual hyst…
Flexo-photovoltaic effect and above-bandgap photovoltage in halide perovskites
Zhiguo Wang, Shengwen Shu, Xiaoyong Wei +4
Halide perovskites have outstanding photovoltaic properties which have been optimized through interfacial engineering. However, as these materials approach the limits imposed by th…
Piezoelectricity in Nominally Centrosymmetric Phases
Oktay Aktas, Moussa Kangama, Gan Linyu +4
Compound phases often display properties that are symmetry-forbidden relative to their nominal, average crystallographic symmetry, even if extrinsic reasons (defects, strain, imper…
Deconvolution of phonon scattering by ferroelectric domain walls and point defects in a PbTiO3 thin film deposited in a composition-spread geometry
David Bugallo, Eric Langenberg, Elias Ferreiro-Vila +7
We present a detailed analysis of the temperature dependence of the thermal conductivity of a ferroelectric PbTiO3 thin film deposited in a composition-spread geometry enabling a c…
Direct visualization of antiferroelectric switching dynamics via electrocaloric imaging
Pablo Vales-Castro, Miquel Vellvehi, Xavier Perpiñà +8
The large electrocaloric coupling in PbZrO3 allows using high-speed infrared imaging to visualize antiferroelectric switching dynamics via the associated temperature change. We fin…
