摘要：

We studied the growth of cobalt on Au(lll) vicinal surfaces in the submonolayer range. We found that the presence of a surface reconstruction leads to interesting self-organized nanostructures, such as very regular arrays of clusters or nanowires. We show that the use of a vicinal substrate strongly improves their long-range order properties. These results, together with the periodic faceting behaviour of gold vicinal surfaces, open the way to fabricate cobalt nanostructures or ultrathin films with original magnetic properties.
