Title: Effect of SrO Doping on LaGaO 3 Synthesis via Magnetron Sputtering

The high temperature growth behavior of epitaxial LaGaO 3 thin films with and without SrO is determined with real-time X-ray scattering. In this study, we find SrO alters the thin film growth mode of LaGaO 3, both when predeposited on a surface as well as when SrO and LaGaO 3 are codeposited. We also find that depositing a small amount of SrO on a LaGaO 3 surface induces significant structural rearrangement in the film. We describe mechanisms under which these transformations can occur. In conclusion, the strong effect of SrO on the microstructure of La 1–xSr xGaO 3 likely has wider implications for other ionically conducting oxide materials.
