Outline of Final Research Achievements

In this study, we focused on ferroelectric nanorods, which can be expected to show different influence of the depolarising field on the domain structure and piezoelectric property as compared with thin films due to the different dimensionality. We experimentally and theoretically investigated them by using Pb(Zr,Ti)O3 [PZT] nanorods with different orientation, size (width) and electrostatic conditions. It was found that the domain fraction of (100)/(001)PZT nanorods can be varied by their size and electrostatic conditions. Furthermore, the polarization-inclined (111)PZT nanorods showed the enhanced piezoelectric response, which can be explained by the depolarising field.
