Two atomic planes shown in the out-of-page direction, where shade indicates the atoms’ relative distance and darker atoms are closer to the reader. Blue and red spheres represent Zr and O atoms, respectively. Produced using VESTA69. Schematics of the oxide microstructure show the normal direction and how it relates to the crystal directions for reference.
