Fig. 3: C54 on a Cu (111) surface.

a–c Final structures of C54 on Cu (111) surface during MD at 1350, 1400, and 1450 K, respectively. Cyan and ochre balls represent C and Cu atoms, respectively. The surrounding melted Cu atoms diffused upwards are highlighted in yellow. d–f Smoothed instantaneous heights of the C54 cluster and the surrounding Cu atoms as a function of MD time at 1350, 1400, and 1450 K, respectively.
