Size Effect for Barium Titanate Nano-particles [Translated]†

概要

論文の詳細を見る
Barium titanate (BT) nano-particles with different diameters were prepared by Sol-Gel method. The particle diameter was determined by XRD, and the lattice constants of nano-particles were also determined by XRD. We also measured the lattice vibration for BT nano-particles by Raman scattering to discuss on the size effect. As a result, we successfully calculated the intrinsic dielectric constants for BT nano-particles by analyzing the lattice vibration. Moreover, we confirmed the shift of Curie temperature by the size effect.† This report was originally printed in J. Soc.
