摘要：

The high temperature growth behavior of epitaxial LaGaO3 thin films with and without SrO is determined with realtime X-ray scattering. We find SrO alters the thin film growth mode of LaGaO3, both when predeposited on a surface as well as when SrO and LaGaO3 are codeposited. We also find that depositing a small amount of SrO on a LaGaO3 surface induces significant structural rearrangement in the film. We describe mechanisms under which these transformations can occur. The strong effect of SrO on the microstructure of Lai,SrxGaO(3) likely has wider implications for other ionically conducting oxide materials.
