(a) Isometric view of the Al-Cu linear complexion sample with L = 10 nm where platelet complexions (A and B) have nucleated at each of the partial dislocations, which are separated by a stacking fault. Views along (b) the dislocation line length and (c) the slip plane normal direction show the platelet complexions growing out of the slip plane at each of the partial dislocations. Atoms are colored according to their local atomic structure (HCP, other, or Cu), while all of the Al atoms with FCC crystal structure have been removed for clarity
