Propriétés diélectriques des céramiques

This cluster of papers focuses on the study of giant dielectric constant materials, particularly CaCu3Ti4O12 and related perovskite oxides. The research covers topics such as the origin of colossal permittivity, internal barrier layer capacitor effects, Maxwell-Wagner relaxation, defect structures, nonlinear electrical behavior, microstructural influences, doping effects, and dielectric relaxations.
