Atomically resolved HAADF-STEM image of an OC type nanoparticle observed in plan-view along a 〈100〉_Fє axis. P_B Au/Fe interfaces are clearly identified at the inner boundaries in the NP, while P_NW and stepped, S, Au/Fe interfaces are found at the outer boundaries. Inset: enlarged view of the grain boundary (GB) formed at the junction between the two Au grains grown over the core cube facets (P_B interfaces), owing to their different orientations. Note the presence of dislocations at this GB.
