Control of Domain States in Individual PbTiO3 Nanoparticles by Prescribed Strains

Abstract:

Article Preview

A three dimensional phase field model has been devised to account for the manipulation of domain states in individual ferroelectric (PbTiO3) nanoparticles. Vortex structures and dipole flux domain patterns were obtained by applying tensile and compressive strains, respectively. The direction of the two domain configurations was found to correlate with the plane on which the strains were applied, mainly due to dipole-strain coupling and depression of depolarizing field.
