Usually,the strain of the strain-release template (e.g.metal bilayer/metal (111) surface) is induced by the inherent lattice mismatch between the substrate and the overlayer [1,2].In this paper,a series of calculations on atomic and electronic structures indicate that the size of the stable metal semi-cluster also makes an important contribution to induce the strain that leads to the periodic template,and to decide the periodic length of the template.The stable (2x2)/(3×3) Pb/Pt(111) is a good candidate to be used as a template,with 8.32 (A) periodic length that is greater than that of the Pb/Cu(lll) template proved in our previous work[2].By carefully selecting different substrate materials and considering the size of the stable semi-clusters,we can tune the periodic length of the template and remain the same material as the adsorbed bilayer.
