Abstract Domain walls and phase boundaries are fundamental ingredients of ferroelectrics
and strongly influence their functional properties. Although both interfaces have been …

Ferroelectric and ferroelastic domain walls are 2D topological defects with thicknesses
approaching the unit cell level. When this spatial confinement is combined with observations …

We present a first-principles study of model domain walls (DWs) in prototypic ferroelectric
PbTiO 3. At high temperature the DW structure is somewhat trivial, with atoms occupying …

Ferroelectric domain walls have emerged as a new type of interface in which the dynamic
characteristics of ferroelectricity introduce the element of spatial mobility, allowing real-time …

Ultradense domain walls are increasingly important for many devices but their microscopic
properties are so far not fully understood. Here we use molecular dynamic simulations to …

This review covers methods and recent developments of the theoretical study of domain
structures in ultrathin ferroelectric films. The review begins with an introduction to some …

Abstract Domain-wall dynamics in ferroic materials underpins functionality of data storage
and information technology devices. Using localized electric field of a scanning probe …

Observation of a new type of nanoscale ferroelectric domains, termed as “bubble domains”—
laterally confined spheroids of sub‐10 nm size with local dipoles self‐aligned in a direction …

Nanoscale ferroelectric topologies such as vortices, antivortices, bubble patterns, etc., are
stabilized in thin films by a delicate balance of both mechanical and electrical boundary …

Phase transition behaviour in ferroelectric materials is strongly dependent on boundary
conditions, both electrical and mechanical. In this article, we cover several topics. Beginning …
