Abstract

In this work, we present a result of PFM measurements on perforated and nonperforated Ba0,8Sr0,2TiO3 thin epitaxial films. A huge enhancement of effective values for both lateral and vertical piezoelectric tensors during polarization reversal was experimentally detected. An assumption of short-range quadrant domain pattern in perforated ferroelectric structure was discussed. The obtained results are crucial for calculations of ferroelectric polarization in ferroelectric photonic crystals and metamaterials.
