The effect of cation stoichiometry and substrate defect density on nucleation, structure, defect formation, and interfacial mixing during III-III perovskite complex oxide heteroepitaxy is explored. Cation imbalance is shown to result in anti-site defect formation within the film, and subsurface cation vacancies promote cation mixing.
