Dynamical Behaviour of Ag and Cu Double-Layer Islands on fcc （111） Surfaces

Molecular dynamics simulations are preformed to investigate the diffusion behaviour of Ag/Cu double-layer islands on Ag(111)/Cu(111) surfaces, showing that atoms of the top island usually diffuse into the lower island by exchange mechanism when they move to the verge of the lower island via a concerted motion. Compared to the Cu adatoms, the Ag adatoms can easily form a kind of stable compact cluster of hexagonal island during their diffusion processes, and this cluster make it possible that the decay rate of the top Ag island is considerably slower than that of the Cu island. In addition, we find that the exchange mechanism is predominant compared to the jumping process in the simple potential calculation. These simulation results are in agreement with previous experimental observations and theoretical calculations.

We perform the calculation of the nucleus–nucleus interaction potential of the dinuclear system with deformed nuclei. Based on the calculated results by properly treating the double-folding method, some results from the analytical expressions for calculating both the nuclear and the Coulomb interactions are investigated. It is concluded that the analytical formula to calculate the Coulomb interaction by Wong [Phys. Rev. Lett. 31(1973)766] can reproduce good double folding results. However the results by the parametrized Morse formula, which are used to calculate the nuclear interaction, greatly deviate from the double folding results, unless the distance of nuclei is adjusted to be shifted to a smaller relative distance determined by the same distance between the nuclear surfaces as one of them pertains to the deformed nuclei. Using the double folding method to calculate the nuclear interaction and employing Wong's analytical formula to calculate the Coulomb interaction can keep good precision and can cost much less computation time.
