Abstract

The dielectric properties of fresh and aged Ba(Zr_0.25Ti _0.75)O₃ thin films have been investigated. It is found that the aged sample shows a significant decrease in the dielectric constant compared to the fresh one. Furthermore, the aged sample also exhibits abnormal double-peaks-shape butterfly C-V characteristics, which indicates the defect-dipole stabilized domain and/or domain-wall motions. Meanwhile, we found that double-peaks-shape butterfly C-V characteristics become weak and even disappear with increasing of applied electric field and temperature. The present results are discussed in light of the symmetry-conforming principle of point defects.
