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

Developing eco-friendly high-performance piezoceramics without lead has become one of
the most advanced frontiers in interdisciplinary research. Although potassium sodium …

Reducing or even prohibiting the use of toxic lead in electronic devices has become one of
the most cutting-edge topics in various disciplines. The recently proposed phase boundary …

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 …

Nanoscale ferroelectrics are expected to exhibit various exotic domain configurations, such
as the full flux-closure pattern that is well known in ferromagnetic materials. Here we …

Ferroelectric domain walls naturally form at nanoscale interfaces of polar order leading to
electronic properties distinct from the bulk that can also be electrically programmed. These …

Piezoresponse force microscopy (PFM) detects the local piezoelectric deformation of a
sample caused by an applied electric field from the tip of a scanning force microscope. PFM …

A novel mesoscale state comprising of an ordered polar vortex lattice has been
demonstrated in ferroelectric superlattices of PbTiO3/SrTiO3. Here, we employ phase-field …

The past few decades have witnessed extensive and intensive studies on ferroelectric
materials with switchable electric polarization due to their broad device applications …
