Domains in ferroelectrics were considered to be well understood by the middle of the last
century: They were generally rectilinear, and their walls were Ising-like. Their simplicity …

The increasing miniaturization of electronics requires a better understanding of material
properties at the nanoscale. Many studies have shown that there is a ferroelectric size limit …

The performance of ferroelectric devices is intimately entwined with the structure and
dynamics of ferroelectric domains. In ultrathin ferroelectrics, ordered nanodomains arise …

The dielectric response of PbTiO 3/SrTiO 3 superlattices is studied using electrical and
structural measurements. While the dielectric response of paraelectric superlattices is well …

The period of polar domain (d) in ferroics was commonly believed to scale with
corresponding film thicknesses (h), following the classical Kittel's law of d∝ h. Here, we …

There is growing evidence that domain walls in ferroics can possess emergent properties
that are absent in the bulk. For example, 180° ferroelectric domain walls in the ferroelectric …

At present, chips urgently need breakthrough development in the power consumption and
integration. The chip integrates billions or even tens of billions of electronic components …

We used x-ray Bragg projection ptychography (BPP) to map spatial variations of ferroelectric
polarization in thin film PbTiO 3, which exhibited a striped nanoscale domain pattern on a …

Ferroelectricity has recently been demonstrated in germanium-based halide perovskites. We
use first-principles-based simulations to study 4–18 nm CsGeBr3 films and develop a theory …

Exploring complex topological structures in condensed matter has shown promising
applications in nanotechnology. Although polar topologies such as chiral vortices and …
