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 …

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

The investigation of two‐dimensional (2D) ferroelectrics has attracted significant interest in
recent years for applications in functional electronics. Without the limitation of a finite size …

Since its inception more than 25 years ago, Piezoresponse Force Microscopy (PFM) has
become one of the mainstream techniques in the field of nanoferroic materials. This review …

It is highly desirable to discover photovoltaic mechanisms that enable enhanced efficiency of
