Fabrication, characterization, properties, and applications of low-dimensional BiFeONanostructures

Abstract

Low-dimensional BiFeOnanostructures (e.g., nanocrystals, nanowires, nanotubes, and nanoislands) have received considerable attention due to their novel size-dependent properties and outstanding multiferroic properties at room temperature. In recent years, much progress has been made both in fabrications and (microstructural, electrical, and magnetic) in characterizations of BiFeOlow-dimensional nanostructures. An overview of the state of art in BiFeOlow-dimensional nanostructures is presented. First, we review the fabrications of high-quality BiFeOlow-dimensional nanostructures via a variety of techniques, and then the structural characterizations and physical properties of the BiFeOlow-dimensional nanostructures are summarized. Their potential applications in the next-generation magnetoelectric random access memories and photovoltaic devices are also discussed. Finally, we conclude this review by providing our perspectives to the future researches of BiFeOlow-dimensional nanostructures and some key problems are also outlined.
