Perovskite oxidenanotubes: synthesis, structural characterization, properties and applications
Abstract
Perovskite oxides exhibit a wide range of functional properties, such as ferroelectricity, piezoelectricity, pyroelectricity, non-linear dielectric behavior, as well as multiferroic property. These properties are indispensable for applications in microelectronic devices. Recent advances in science and technology of perovskite oxides have resulted in the feature sizes of microelectronic devices down-scaling into nanoscale dimensions. At the nanoscale perovskite oxides display novel physical properties that are different from their bulk and film counterparts. Understanding these size effects of perovskite oxides at the nanoscale is of importance for the developing a new generation of revolutionary electronic nanodevices. Due to these effects being dependent on the structure and finite size, considerable efforts have been made in the controllable synthesis of low-dimensional perovskite
