(a) Simulated decahedral Au-Cu core-shell nanoparticle, where a partial atomic layer has been formed at the vicinity of the vertices of the particle. (b) STEM simulated micrograph of the particle in Figure (a) where white ovals represent partial layers. The regions with the partial atomic layers appear as lattice mismatches in the micrograph, just as in Figure 6. (c) Intensity profile along the twin boundary of STEM simulated image (along white arrow in Figure 7(b)), where the disparity of the intensity in the Au-rich and Cu-rich atomic columns can be observed.
