Abstract

The electrical conductivity of CaTiO3: Sc ceramics increases with time under a dc-bias voltage of ≤100 V cm−1 and at 300–600 °C. The conductivity increase is reversible on removal of the dc bias. This low-field effect, is independent of electrode materials and atmosphere, and is attributed to ionization of underbonded O2− ions adjacent to acceptor-doped Sc3+ ions on application of a dc bias. Conduction is predominantly p-type and therefore, holes located on oxygen, as O− ions, are the principal charge carriers.
