Symposium EL11—Lead-Free Ferroelectrics and Their Emerging Applications
Ferroelectric materials have diverse functionalities that enable numerous applications ranging from ferroelectric memory to energy harvesting, which have attracted continuous R&D interests. In particular, as an important member of the ferroelectric family, piezoelectric materials play an important role in various kinds of modern electronic devices, such as sensors, transducers and piezoelectric actuators. From the viewpoint of environmental protection and human health, high-performance lead-free piezoelectric ceramics have stimulated huge amounts of related materials research in past decades. More recently, there is a continuously increasing demand for high-power energy storage devices, in which dielectric and ferroelectric/antiferroelectric materials have many advantages such as fast charge and discharge processes compared to batteries and supercapacitors. Also, depending on doping, lead-free ferroelectrics can either serve as high-temperature capacitors or as oxygen conductors posing intriguing questions with respect to local structure. This symposium will cover the research frontier in ferroelectric materials from lead-free piezoelectrics, high-power energy storage materials to emerging applications. Both, world-wide active scientists and young professionals are scheduled to join for reporting and discussing hot topics in this field, including basic science issues, new phenomena, new materials, synthesis processes, characterization, and applications.
