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…
