| Outline of Final Research Achievements |
This project is based on our recent finding of a highly piezoelectric Pb-free material BZT-BCT (Phys. Rev. Lett. 2009) and aimed at clarify its physical origin and thus desiging highly piezoelectric and yet high Tc Pb-free piezoelectrics. We have essentially achieved the goal and the main achievements are as follows.
1. We have clarified the origin of highly piezoelectric BZT-BCT material using TEM and CBED techniques.
2. The understandingg of the origin of high piezoelectricity helps to design a new Pb-free piezoelectric with both high piezoelectricity and high Tc. (Patent in processing)
