Abstract

The high dielectric constant in “SrCu3Ti4O12” and the giant dielectric constant in CaCu3Ti4O12 are based on a barrier layer mechanism. Conductivity in the conducting regions is related to Ti on Cu sites. The insulating barriers are between crystallites in “SrCu3Ti4O12” but within the crystallites in CaCu3Ti4O12.
