Oxide electronics relies on the availability of epitaxial oxide thin films.\nThe extreme flexibility of the chemical composition of ABO3 perovskites and the\nbroad spectrum of properties they cover, inspire the creativity of scientists\nand place perovskites in the lead of functional materials for advanced\ntechnologies. Moreover, emerging properties are being discovered at interfaces\nbetween distinct perovskites that could not be anticipated on the basis of\nthose of the adjacent epitaxial layers. All dreamed new prospects require the\nuse of suitable substrates for epitaxial growth. Perovskite single crystals are\nthe workhorses of this activity and understanding and controlling their surface\nproperties have become critical. In this tutorial review we will chiefly focus\non the impact of the morphology and composition of the surface of ABO3\nperovskite substrates on the growth mechanisms and properties of thin films\nepitaxially grown on them. As SrTiO3 is the most popular substrate, we will\nmostly concentrate on describing the current understanding and achievements for\nit. Illustrative examples of other perovskite substrates (LaAlO3, LSAT and\nDyScO3) will be also included. We will show that distinct chemical terminations\ncan exist on the surfaces used for growth and we will review methods employed\neither to select the most appropriate one for specific growth to allow, for\ninstance, tailoring the ultimate outmost epilayer, or to induce self-ordering\nto engineer long-range nanoscale patterns of chemical terminations. We will\ndemonstrate the capacity of this knowledge by the growth of low-dimensional\norganic and inorganic structures.\n
