Article Description

Size effect on uniaxial stress affecting dielectric response in barium titanate system is studied in this paper. From experiments we know that, dielectric constant decreases with increasing loading stress. The change rates of dielectric constants for different grain sizes are different, samples with finer grains have smaller change rate. In theory, we can derive out that dielectric constant will decrease with loading stress by Landau-Ginsberg- Devonshire model. Furthermore, the grain size effect is analyzed with a complex model. The volume fraction of the grain boundaries will increase, and they will bear more part of the total loading when decreasing grain size. This will reduce the change rate of dielectric constant for finer grains. © 2010 The Japan Society of Applied Physics.
