Domain boundaries typically constitute only a minute fraction of the total volume of a crystal.
However, a special (but not unusual) situation can occur in which the domain boundary …

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 …

Dynamics of crystals is a subject of recent interest in solid-state physics and a challenge for
modern X-ray crystallography. Time-dependent response of solids to an external …

Large reversible changes of thermal conductivity are induced by mechanical stress and the
corresponding device is a key element for phononics applications. We show that the thermal …

Domain boundaries in lead phosphate, P b 3 (PO 4) 2, are investigated by using second
harmonic generation (SHG) microscopy. It is revealed that they are polar while the bulk is a …

KTaO 3 is an incipient ferroelectric material with an extrapolated transition temperature
below 0 K. It contains a small number of “unavoidable defects” which are randomly …

Mechanical properties of ferroelectric materials at the nanoscale have received growing
interest over the past years due to new developments in scientific instrumentation and novel …

Domain boundary engineering endeavors to develop materials that contain localized
functionalities inside domain walls, which do not exist in the bulk. Here we review …

The effect of doping metal ions in ferroelastic Pb 3 (PO 4) 2 (PPO) on the polar nature of
domain boundaries (DBs) was investigated using a second harmonic generation (SHG) …

Cerium‐doped yttrium aluminum garnets (Y3‐xCexAl5O12, Ce: YAGs) are promising yellow
light‐emitting components of solid‐state white light‐emitting diodes. Although there have …
