The effect of excess electron on the per atom formation energies of the low energy Au12–14 clusters identified in Tables 1, 2 and 3.
Formation energies are shown for 56 structures. The clusters are given in the same order as in Tables 1, 2 and 3 for Au12 (structures 1–9), Au13 (structures 10–30) and Au14 (structures 31–56). The vertical dashed lines separate one cluster size from another. Empty and filled symbols are used for 2D and 3D structures respectively.
