Interplay between Point and Extended Defects and Their Effects on Jerky Domain-Wall Motion in Ferroelectric Thin Films

Author(s): Ralph Bulanadi, Kumara Cordero-Edwards, Philippe Tückmantel, Sahar Saremi, Giacomo Morpurgo, Qi Zhang, Lane W. Martin, Valanoor Nagarajan, and Patrycja Paruch Defects have a significant influence on the polarization and electromechanical properties of ferroelectric materials. Statistically, they can be seen as random pinning centers acting on an elastic manifold, slowing domain-wall propagation and raising the energy required to switch polarization. Here … [Phys. Rev.
