Figure 5

Plot of potential energy (PE) of Ag shell (blue), Cu core (red) and whole structure (black) during heating of Ag\({}_{132}\)Cu\({}_{147}\) at 50 K for 2500 ps. The energy is measured relative to mean of the respective component. The solid lines indicate the energy values after smoothing of the actual energy data (dotted lines). Anti-Mackay, chiral icosahedron structures are indicated by aM, c respectively. Also included in this figure are the structures of the nanoalloy with anti-Mackay (aM) stacking and the chiral (c) stacking observed during the heating. The chiral stacking can have either clockwise or anti-clockwise rotation of the {111}-like planes.
