Ferroelectric Domain Reversal: The Role of Domain Wall Conduction

Ferroelectric domain reversal is a vast research area relevant to the fundamental science and applications as well macro- nanoscales. An instantaneous compensation of typically huge depolarizing electric fields key element here. On other hand, wall (DW) conduction now regarded general ferroelectric phenomenon. Being often separated by big surface energy barriers in macroscopic experiments, DW becomes easily available under conditions atomic-force microscopy. We claim that has be crucial ingredient processes. Its importance providing an automatic fields. The presence essentially modifies basics processes, including relations for nucleus energies, grows velocities, shapes. Concerning microscopy applications, theories have include injection models from conductive tip electrodes. Below we provide specific primary results mediated reversal.
