Abstract: Ferroelectricity on the nanoscale has remained a subject of
much fascination in condensed matter physics for the last several
decades. It is well-recognized that stability of the ferroelectric state
necessitates effective polarization screening, and hence screening
mechanism and screening charge dynamics become strongly coupled to
ferroelectric phase stability and domain behavior. Previously, the role
of the screening charge in macroscopic ferroelectrics was observed in
phenomena such as potential retention above Curie temperature, back
switching of ferroelectric domains, and chaos...
