摘要：
Numerical simulations of generation and aggregation of BaTiO3 nanoparticles have been performed under the experimental condition of Dang et al. [Jpn.J.Appl.Phys. 48, 09KC02 (2009)] in order to study the mechanism of mesocrystal formation. It is shown that electric dipole-dipole interaction model sufficiently reproduces the experimental results of the oriented aggregation of BaTiO3 nanocrystals. It is suggested that 5 nm BaTiO3 nanocrystals synthesized under ultrasound have spontaneous polarization.
