Oxide-Ion Conduction in the Dion-Jacobson-Type Layered Perovskites

A study of Dion–Jacobson-type layered perovskite oxides has discovered high oxide-ion conductivities in phases for the first time, making them important for energy conversion devices and environmental protection applications. The discovery was made possible by a new screening method and an original design concept, and a deep understanding of the mechanisms of oxide-ion diffusivity at an atomic level in the Dion–Jacobson phases is clarified.
