Polarity and anti-distortive polarons in WO3 through epitaxial shear strain
Ewout van der Veer, Martin F. Sarott, Jack T. Eckstein +11
Bestowing CMOS-compatible binary oxides with additional functionalities is a powerful strategy toward the realization of oxide electronics. Ideal candidates are thin films which di…
Antiferroelectric switching inside ferroelastic domain walls
Guangming Lu, Gustau Catalan, Ekhard K. H. Salje
Ferroelastic materials (materials with switchable spontaneous strain) often are centrosymmetric, but their domain walls are always polar, as their internal strain gradients cause p…
From phonons to domain walls, the central peak and critical slowing down
Ekhard K. H. Salje, Annette Bussmann-Holder
We investigate perovskite oxides from different aspects, namely their pseudoharmonic dynamical properties, their dynamical properties when strong anharmonicity exists and the intri…
Evidence of the Monopolar-Dipolar Crossover Regime: A Multiscale Study of Ferroelastic Domains by In-Situ Microscopy Techniques
John J R Scott, Guangming Lu, Brian J. Rodriguez +3
The elastic interaction between kinks (and antikinks) within domain walls plays a pivotal role in shaping the domain structure, and their dynamics. In bulk materials, kinks interac…
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…
Periodicity doubling cascades: direct observation in ferroelastic materials
Arnoud S. Everhardt, Silvia Damerio, Jacob A. Zorn +6
Very sensitive responses to external forces are found near phase transitions. However, phase transition dynamics and pre-equilibrium phenomena are difficult to detect and control.…
