Synergistic Grain Refinement and Insulating Phase Formation via Zr4+ Doping for Low-Loss Colossal Permittivity in (In,Nb) Codoped TiO2 Ceramics

Abstract Colossal permittivity (In,Nb) codoped TiO2 ceramics are promising for microelectronic applications but suffer from high low-frequency dielectric loss primarily due to leakage currents across grain boundaries. This work demonstrates that Zr4+ doping at Ti-sites in (In0.5N...
