Abstract

The morphological evolution of a Co cluster deposited on a Cu substrate is investigated by means of molecular-dynamics simulation. The many-body potential based on the second moment approximation of a tight-binding Hamiltonian (TB-SMA) is employed to calculate the interactions between Co and Cu atoms. The results show that the effect of the substrate anisotropy appears in the morphology of a deposited cluster. It is also revealed that the total period of the structural change of such a cluster can be divided into the three stages, viz., (I)change to an epitaxial structure, (II)overspread of diffusing Cu atoms on the cluster, and (III)solid dissolution of Co atoms into the Cu substrate.
