Piezoelectric and ferroelectric/multiferroic materials play an important role in various kinds of modern electronic devices, such as sensors, transducers and piezoelectric actuators. Following sustained research efforts over the past decades, piezoelectric and ferroelectric/multiferroic materials are continuing to provide an ever-changing landscape with exciting developments. From the viewpoint of environmental protection on Earth, high-performance lead-free piezoelectric ceramics are one of the most urgent demands, which have stimulated huge amounts of related materials research in past decades. At the same time, driven by a combination of new experimental and theoretical tools, research on ferroelectric and multiferroic materials has made great progress. For example, breakthroughs have been made in bulk and nanoscale ferroic materials, including the voltage control of nanomagnetism, the emergence of robust ferroelectricity in strained ultrathin nanoscale gate dielectrics, the stabilization and manipulation of topological states in oxide ferroics, which represent the frontier in the understanding of quantum phenomena of matter. Furthermore ferroelectric and multiferroic materials are expected to produce revolutionary applications in many technological fields, such as electronics, information, sensing, actuation and even new neuromorphic computing, and artificial intelligence in the future. Many international governments (such as the U.S. Department of Energy, etc.) and companies (such as Intel, Samsung, etc.) have invested a great deal of effort in striving for scientific and technological breakthroughs that will in turn replace the existing traditional electronic material systems and processes. Chinese scientists have also made important contributions in this field. This symposium will focus on recent developments in the physics, materials science and applications of piezoelectric, ferroelectric and multiferroic materials and devices.
