dc.description.abstractThe electrical degradation and relaxation behaviors of Ho-doped BaTiO3 with excess BaO have been studied in terms of oxygen vacancy concentration, leakage current, microstructure and thermally stimulated depolarization Current (TSDC). Within the solubility limit (similar to 3.0mol%), Ho3+ ions effectively increased the number of oxygen vacancies in Ba(Ti1-xHox)O3-0.5x. Leakage current increased with Ho content and the highest leakage current appeared in Ba(Ti0.98Ho0.02)O-2.99. The oxygen vacancy mobility in Ho-doped BaTiO3 specimens was significantly increased compared with that in undoped BaTiO3. The TSDC in Ba(Ti1-xHox)O3-0.5x increased with Ho content and the highest TSDC peak occurred at the specimen with 2.0mol% Ho. The activation energies for depolarization current related to the motion of oxygen vacancies in Ba(Ti1-xHox)O3-0.5x were calculated to be 0.60-0.64eV.-
