The last sentence of the abstract in Ref.[M. Mantilla, N. Jedrecy, R. Lazzari, and J. Jupille, e-J. Surf. Sci. Nanotech. 7, 476 (2009).] should be corrected as follows: “A hexagonal array of dots with a 4.5 nm periodicity may even be obtained, which we attribute to an epitaxial Mg-O (111) layer with in-plane spacing equal to either 0.3 or 0.32 nm.” [DOI: 10.1380/ejssnt.2009.529]
