Epitaxial thin films have been grown by pulsed-laser deposition on (110)Pt bottom electrode epitaxially grown on (110) by dc sputtering. X-ray φ-scans and electron channeling patterns reveal the epitaxial growth of the (116) bilayers. The hysteresis loop, dielectric response, and capacitance–voltage characteristics of this bilayer are presented. The remnant polarization was measured to be close to 5 μC/cm2, and the coercive field was calculated to be ∼120 kV/cm. The zero field permittivity was about 150 and the dielectric loss was ∼2%.

The actual orientation is nearly (116)SBN, with an angular deviation of 0.2°, as discussed in detail in Ref. 19. In this report the orientation is denoted as (116) for clarity.
