Distinct roles between complex defect clusters and insulating grain boundary on dielectric loss behaviors of (In3+/Ta5+) co-doped CaCu3Ti4O12 ceramics

Distinct roles between complex defect clusters and insulating grain boundary on dielectric loss behaviors of (In3+/Ta5+) co-doped CaCu3Ti4O12 ceramics

The effects of (In3+/Ta5+) co-dopants on the crystalline structure, microstructure, dielectric response, and electrical properties of CaCu3Ti4-x(Ta0.5In0.5)xO12 ceramics are investigated. By increasing co-doping concentration, the lattice parameter is enlarged, while the mean grain size (98.6 → 11.3...
