Strategy for lead-free ferroelectric and piezoelectric materials with perovskite-type structure was obtained based on the new idea based on the chemical bonds and crystal structures. As a result, many candidate materials were found out as well as new interpretation on the mechanism for the evolution of known ferroelectric materials. Thin films of novel compounds, which are not available by the conventional solid state technique, were also successfully obtained by the pulsed laser deposition technique.

基于化学键和晶体结构的新思想，提出了钙钛矿型结构无铅铁电压电材料的制备策略。结果发现了许多候选材料，并对已知铁电材料的演化机制提出了新的解释。新型化合物的薄膜，这是不能通过传统的固态技术，也成功地获得了脉冲激光沉积技术。
