Dipole-Dipole Interaction Model for Oriented Attachment of BaTiO₃ Nanocrystals Revisited

Abstract:

Numerical simulations of the oriented aggregation of BaTiO₃ nanocrystals using the dipole-dipole interaction model have been performed under conditions corresponding to those used in ultrasound-assisted synthesis. The results suggest that BaTiO₃ nanocrystals with a diameter of 5 nm have a spontaneous polarization that is not more than one order of magnitude lower than the value of ~0.15 C/m² for a macroscopic BaTiO₃ single crystal.
