Invited Talk: Jing-Feng Li (Toyota Research Center Tsinghua University, China) - Lead-free ferroelectric and antiferroelectric niobate ceramics

Apr 22
22. April 2021 11:00 Uhr bis 11:30 Uhr

Invited Talk of the IRTG “Energy Conversion Systems” ( )
This talk will introduce lead-free niobate-based perovskites including (K,Na)NbO3 and AgNbO3, both of which have been lying at the forefront of functional oxide research. (K,Na)NbO3 (abbreviated as KNN)is a promising lead-free ferroelectric/piezoelectric system, centering on which this talk will give a review about how high-performance piezoceramics have been developed. Based on our recent research about AgNbO3, I will also introduce antiferroelectricity and discuss its underlying connections with high piezoelectricity and dielectric energy storage performance.
