| Outline of Final Research Achievements |
In this study, unique ferroelectric polarization patterns emerged in nano-metamaterials and their mechanical and/or electric responses are investigated. A variety of polarization ordering, such as cross-, vortex-, and labyrinth-types, can be emerged in nano-metamaterials depending on their microstructures. These unique polarization patterns can be mainly classified into 4 groups. Associated with the emergence of unique polarizations, novel properties such as electro-mechanical response opposite to homogeneous counterparts and multi-hysteresis loops via electric field can be emerged.
