Expanding the numberof atomically flat perovskite-type oxides: controlled selective wet etching of rare-earth scandates results in single-terminated, well-defined surfaces. Using the powerful combination of time-of-flight mass spectroscopy and the morphology study of SrRuO3 thin-film growth, complete ScO2-termination of the surfaces is established.
