aandbLattice images of Au rolls developed from the corrugated area (arrowed) in Fig. 5g after electron irradiation for 1 and 5 min, respectively, showing progressive corrugation and separation into spherical onions. The intensity profiles of the lattice images along the tracesarrowed(insets) show varied intensity and interspacings from core to shell due to dislocations and atom clusters within the onions
