中文摘要 | We investigate in detail the migration kinetics of oxygen vacancies (OVs) in Ba-doped Pb(Zr(0.52)Ti(0.48))O(3) (PZT) ferroelectrics by complex impedance spectroscopy. The temperature dependent dc-electrical conductivity sigma(dc) suggests that Ba doping into PZT can lower significantly the density of OVs, leading to the distinctly decreased sigma(dc) and slightly enhanced activation energy U for the migration of OVs, thus benefiting the polarization fatigue resistance. Furthermore, the polarization fluctuation induced by the relaxation of OVs is reduced by the Ba doping. The Cole-Cole fitting to the dielectric loss manifests strong correlation among OVs, and the migration of OVs appears to be a collective behavior. |
