Recently, non-perovskite-type ferroelectrics has been paid much attention. Bi₂SiO₅ is one of the new ferroelectrics without perovskite structure, which is a layered structure of Bi₂O₂^2- and SiO₃²⁺. We have reported that non-a-axis oriented Bi₂SiO₅ thin film has a ferroelectric feature. In this study, the effects of growth conditions of epitaxial thin films on lattice parameters was investigated.
