This method discovered major distortions of RuO6 and ScO6 octahedra with the heterointerface between a SrRuO3 movie and also a GdScO3 substrate. We also located that structural mismatch was relieved in only four device cells near the interface by shifting the oxygen atomic positions to accommodate octahedral tilt angle mismatch. https://crithitceramics.com/allies/
