EngineeringIntermediate Phases in Topotactic PhaseTransitions of Cobaltite Perovskites

Abstract Topotactic phase transitions in perovskite cobaltites (R1–xAxCoO3−δ; R = rare earth, A = alkaline-earth ion) play a key role in the operation of neuromorphic devices, where oxygen vacancy concentration (δ) modulates resistive switching. However, the emergence of an insul...
