Leading Role of Grain Boundaries in Colossal Permittivity of Doped and Undoped CCTO

Journal of the European Ceramic Society, 2014
Abstract The role of grain boundaries in the colossal permittivity ɛ of doped and undoped calcium copper titanate, CaCu3Ti4O12 (CCTO), is illustrated by a first correlation – over four orders of magnitude – between ɛ and the capacity of grain boundaries, not that of grains, deduced from the analysis of impedance measurements. The DC resistance of the

The Self-Compensation Mechanism in Barium Titanate Ceramics With Colossal Permittivity

Journal of Alloys and Compounds, 2021
Abstract Based on adjusting the relationship between polarization and charge carriers, barium titanate (BaTiO3) ceramics with colossal permittivity and high insulation resistivity are prepared by solid-state reaction approach. Modified by reducing atmosphere (0.1%H2/N2) and donor-ions doping, different polarization modes are discussed via treatment ...

Colossal Dielectric Permittivity in Hydrogen-Reduced Rutile TiO2 Crystals

Journal of Alloys and Compounds, 2017
Abstract (Nb + In) co-doped rutile TiO2 (TINO) ceramics have received considerable attention, due to their high dielectric permittivity (on the order of 10,000) and low loss factor (
