... change of the lowest -energy structure is much slower than that on Cu(110) with the cluster size increasing. Corresponding to the type change of the lowest -energy structure, the low- energy structures ... [2-10]. However, such studies mainly focus on the lowest -energy structures. For the structures with energy close to the lowest one, which are named low- energy structures here, investigations and discussions ... we can predict the type change of the lowest -energy structure. Still take Cu(110) as an example (ξ = 5.26), from Equation 11, the change of the lowest -energy structure from one linear chain...
