Anomalous Increase of Dielectric Permittivity in Sr-Doped CCTO Ceramics Ca1−xSrxCu3Ti4O12 (0 ≤x ≤ 0.2)
Source abstract
Abstract
Partial substitution of Ca with Sr in high permittivity Ca1−xSrxCu3Ti4O12 ceramics can lead to an anomalous increase in intrinsic bulk dielectric permittivity. The similar electron configuration of Ca and Sr excludes electronic structure variations as a source of this permittivity increase, and thus an alternative mechanism must exist.
