Schematic representation of Sr2IrO4 thin films interfaced with various substrates, including ruthenates single crystals and reference LSAT substrates. Sr2RuO4 and LSAT single crystals have comparable in-plane lattice constants but exhibit distinct electronic properties, with Sr2RuO4 being metallic and LSAT insulating. The Ca3Ru1.98Ti0.02O7 single crystal has a temperature-dependent metal-insulator transition, exhibiting metallic behavior above 55 K and becoming insulating below this temperature.
