(Figure Presented) We investigated the ferroelectric characteristics of an epitaxial perovskite ZnSnO3 thin film on a (111) SrRuO 3/(111) SrTiO3 substrate fabricated by pulsed laser deposition. We confirmed that the ZnSnO3 thin film was epitaxially grown on the substrate, forming large terraces on the surface of the ZnSnO 3 thin film. The ZnSnO3 thin film exhibited a high ferroelectric polarization of ∼47 μC/cm2, which was further supported by first-principles calculations.
