(a) HAADF and (b) ABF images simultaneously taken along the [110] zone axis with the Cs-corrected STEM. The framed area corresponds to the projection of the unit cell. (c) and (d) Magnified images of the parts indicated by a solid frame in (a) and (b). (e) HAADF and (f) ABF images calculated with the structural parameters reported by Belin et al. (Belin & Belin, 2000). (h) HAADF and (i) ABF images calculated with the structural parameters refined in the present study. The corresponding portion of [110] projection of the structural models (g) reported by Belin et al. (Belin & Belin, 2000) and (j) refined in the present study. |
