AB The subtle balance of electronic correlations, crystal field splitting, and spin–orbitcoupling in layered Ir4+ oxides can give rise to novel electronic and magnetic phases.Experimental progress in this field relies on the synthesis of epitaxial films of theseoxides. However, the growth of layered iridates with excellent structural quality isa great experimental challenge. Here we selectively grow high quality single-phasefilms of Sr2IrO4, Sr3Ir2O7, and SrIrO3 on various substrates from a single Sr3Ir2O7target by tuning background oxygen pressure and epitaxial strain. We demonstratea complex interplay between growth dynamics and strain during thin film deposition. Such interplay leads to the stabilization of different phases in films grown ondifferent substrates under identical growth conditions, which cannot be explained bya simple kinetic model. We further investigate the thermoelectric properties of thethree phases and propose that weak localization is responsible for the low temperatureactivated resistivity observed in SrIrO3 under compressive strain
