as a result of their fascinating physical behaviors and promising applications in the field of …

Despite being applied with success in many fields of materials science, Raman
spectroscopy is not yet determinant in the study of electroceramics. Recent experimental …

Flexoelectricity is a type of ubiquitous and prominent electromechanical coupling, pertaining
to the electrical polarization response to mechanical strain gradients that is not restricted by …

We study, by means of an atomistic toy model, the interplay of ferroelastic twin patterns and
electrical polarization. Our molecular dynamics simulations reproduce polarity in straight …

The emergence of a domain wall property that is forbidden by symmetry in bulk can offer
unforeseen opportunities for nanoscale low-dimensional functionalities in ferroic materials …

In this Perspective, two interrelated new developments are discussed. The first relates to a
much better understanding of the actual movement of domain walls during switching …

Devices operating at GHz frequencies can be based on ferroelectric kink‐domains moving
at supersonic speed. The kinks are located inside ferroelastic twin boundaries and are …

The elastic interaction between kinks (and antikinks) within domain walls plays a pivotal role
in sha** the domain structure, and their dynamics. In bulk materials, kinks interact as …

The non-smooth, jerky movements of microstructures under external forcing in minerals are
explained by avalanche theory in this review. External stress or internal deformations by …

Ferroelastic domain walls are typically twin interfaces. They contain a multitude of emerging
properties, including (super-) conductivity, polarity, optically activity, and photovoltaic …
