Perovskite solid solutions with multiferroic morphotropic phase boundaries and property enhancement [PDF]

open access: yesJournal of Advanced Dielectrics, 2016
Recently, large phase-change magnetoelectric response has been anticipated by a first-principles investigation of phases in the BiFeO3–BiCoO3 perovskite binary system, associated with the existence of a discontinuous morphotropic phase boundary (MPB ...

From Heterostructures to Solid‐Solutions: Structural Tunability in Mixed Halide Perovskites

open access: yesAdvanced Materials, 2023
AbstractThe stability, reliability, and performance of halide‐perovskite‐based devices depend upon the structure, composition, and particle size of the device‐enabling materials. Indeed, the degree of ion mixing in multicomponent perovskite crystals, although challenging to control, is a key factor in determining properties.
