Structures and magic numbers of adatom clusters on metal fcc (001) surfaces

Theoretical Study of YnO2 and YnO2− (n = 1−8) Clusters

“…This explanation has recently been proposed by Zhang et al They suggest that the effect of temperature sometimes cannot be ignored in finding the most stable structures of clusters. 18 In addition, another possible isomer for Y 2 O 2 -, which is probably a neutral Y 2 unit with a side-bonded peroxide (O 2 2-) anion, was also predicted in the experiment. 11 clusters O atom prefers to keep its two single bonds.…”

Reliable Lateral Manipulation of Single Adatom on Metal fcc (111) Surfaces with a Single-Atom Tip

“…Using these potentials, we have already achieved success in the studies of atom diffusions and structure of adatom clusters on several metal fcc surfaces. [34,35] In this work, we obtain the similar results for both the kinds of potentials, and those from the EAM potential are given. We consider that the manipulation is successful if the adatom is moved following the tip and remains on the surface after the tip is retracted from the surface, while the tip keeps intact in the whole process.…”

Ostwald ripening of faceted two-dimensional islands

“…Calculations with realistic model potentials show that magic sizes are inherent to metal fcc ͑001͒ surfaces. 24 It was shown theoretically that the presence of magic island sizes disrupts the scaling law of submonolayer molecular beam epitaxy growth. 25 Magic sizes of threedimensional Pb nanocrystals on Si͑111͒ lead to a breakdown of the classical Ostwald ripening laws.…”
