(a) Low-magnification TEM image of cubic Au NCs. (b₁–b₆) High-magnification TEM images of individual cubic Au NCs viewed from different orientations, with the corresponding atomic models shown on the bottom of each TEM image (b₁, b₂: [100], b₃, b₄: [110], and b₅, b₆: [111]). (c) Lattice-resolved HRTEM image of cubic Au NCs collected along the [100] direction. (d) Atomic resolved HAADF-STEM image of cubic Au NC {100} facets, with (e) its corresponding FFT pattern along the [100] zone axis. (f) Low-magnification TEM image of T-OCT Au NCs. (g₁–g₆) High-magnification TEM images of individual T-OCT Au NCs viewed from different orientations, with the corresponding atomic models shown on the bottom of each TEM image (g₁, g₂: [100], g₃, g₄: [110] and g₅, g₆: [111]). (h) Lattice-resolved HRTEM image of T-OCT Au NCs taken along the [111] direction. (i) Atomic resolved HAADF-STEM image of T-OCT Au NC {111} facets, with (j) its corresponding FFT pattern along the [111] zone axis. Insets of (d) and (i) are the simulated atom arrangements of the {100} and {111} facets.
