Material Study of High Performance Single Crystal Ferroelectric Nanowires

Ferroelectric materials, which exhibit switchable polarization and are piezoelectric, have been extensively studied because of their applications in nonvolatile memory and energy harvesting devices.[1,2] Recently, ferroelectric nanostructures have attracted great interest as they provide a platform to investigate the size effect of ferroelectricity and enable integration with prevailing miniature electronic devices. Characterizations of properties such as piezoelectric coefficient and domain structure are essential to understand nanoscale ferroelectricity and ultimately device integration.[3]
