　　报告题目： A road to large strain in a lead-free piezoelectric material

　　内容简介： In this talk, he will introduce the formation of a morphotropic phase boundary through epitaxial constraint in lead-free ferroelectric BiFeO₃, the nanoscale origin of the ultrahigh electromechanical coupling, the observed large strain value without dielectric breakdown and the understanding of the origin of this nanoscale phase transition, which are very valuable for designing new and improved materials for next generation lead-free piezoelectric devices.
