Ferroelectric behavior in strained SrTiO3 nano porous is investigated using phase-field method. We find, in the strained nano-porous, ferroelectric regions with some polarization vortices emerge around each pore. The ferroelectric region expands and connects each other with increasing strain, and finally forms a periodic structure in which the polarization vortex arrays with the unusual pattern. These findings suggest that we can mechanically tailor complex shape ferroelecirc nano structures, which leads to new functional devices.
