High energy storage and colossal permittivity CdCu3Ti4O12 oxide ceramics

Zhanhui Peng et al.

Summary: In this study, an effective strategy was adopted to enhance the breakdown field strength (E-b) in CdCu3Ti4O12(CdCTO) ceramics using a semi-wet chemistry technique, resulting in a significant increase in energy storage density (W) while maintaining high permittivity. The decreased grain size formed upon SiO2 doping significantly enhanced grain boundary resistance (R-gb), leading to acceptable dielectric properties and energy storage performances.

Giant dielectric response and relaxation behavior in (Tm plus Ta) co-doped TiO2 ceramics

Jiangtao Fan et al.

Summary: In this work, Tm + Ta co-doped TiO2 ceramics with ultrahigh permittivity and very low loss were prepared using a solid-state reaction method. The high dielectric constant and low dielectric loss were attributed to the electron pinned defect dipole response formed by the coupling of Ti3+ and oxygen vacancies. The impedance analysis and frequency dependent dielectric constant under a DC bias suggested that the internal barrier layer capacitance response and electrode response also contribute significantly to the dielectric constant.
