Fig. 4. Spherical-aberration corrected field emission TEM images of GIrNC and EDS elemental mappings from a TEM image. (a) A low-magnification TEM image, (b) a high-resolution TEM image, (c) an enlarged fragment taken from (b) (shown by the square symbol), (d) a marked area for EDS elemental mapping, (e–g) EDS elemental mappings from the marked area.
