(a) Projection on the crystallographic ab plane of the basic melilite structure (four unit cells are shown); (b) high-voltage, high-resolution transmission electron micrograph of a thin specimen area of a Co-melilite crystal with the Fourier power spectrum inset; (c) magnified region squared with the dotted line in Fig. 1(b); (d) multi-slice image simulation with a defocus value of Δf = 80 nm and the specimen thickness t = 3.5 nm. |
