Freestanding Perovskite Oxide Films: Synthesis, Challenges, and Properties

In this review paper, recent progress in the fabrication, transfer, and fundamental physical properties of freestanding oxide perovskite thin films is discussed. First, main strategies for synthesis transfer are analyzed. initial section, particular attention devoted to use water-soluble (Ca,Sr,Ba)3Al2O6 as sacrificial layers, one most promising techniques fabrication membranes. The functionalities that have been observed then reviewed. doing so, authors begin by describing emergence new phenomena ultrathin membranes when released from substrate. They move on a summary functional under application strain. Indeed, offer unique possibility actively control strain state far beyond what can be with traditional methods, allowing investigation profound interplay between structural electronic oxides. Overall, highlights potential oxide-based become preferred platform study novel materials.
