2. See for example R. Weissmann, K. Müller, Surf. Sci. Rep. 1 (1981) 251 and references therein. In particular the early work of T.F. Gallon, Surf. Sci. 17 (1969) 485.
3. Some examples beyond many others of systems which are more or less far from the layer by layer behaviour: (a) Ag/Si(111): Q.-G. Zhu, A.-D. Zhang, E.D. Williams, R.L. Park, Surf. Sci. 172 (1986) 433; (b) Cu/ZnO(0001)-O: K.H. Ernst, A. Ludviksson, R. Zhang, J. Yoshihara, C.T. Campbell, Phys. Rev. B 47 (1993) 13782; (c) Pd/MgO(001): C. Goyhenex, M. Meunier, C.R. Henry, Surf. Sci. 350 (1996) 103; (d) Ag/MgO(001): P. Guénard, G. Renaud, B. Vilette, Physica B 221 (1996) 205; O. Robach, G. Renaud, A. Barbier, P. Guénard, Surf. Sci. 377–379 (1997) 958; (e) Ag/TiO2(110): D. Martin, F. Creuzet, J. Jupille, Y. Borensztein, P. Gadenne, Surf. Rev. Lett. 5 (1998) 321; (f) Cu/Al2O3: M. Gautier, L. Phan Van, J.P. Duraud, Europhys. Lett. 18 (1992) 175; S. Gota, M. Gautier, L. Douillard, N. Thromat, J.P. Duraud, P. Le Fèvre, Surf. Sci. 323 (1995) 163; (g) Fe/MgO: K. Thrümer, R. Koch, M. Weber, R.H. Rieder Phys. Rev. Lett. 75 (1995) 1767; (h) for metal/metal systems see Refs. [4] and [5].
4. Typical examples are the Co/Cu(100) and (111) systems, first interpreted as layer by layer growth: L. Gonzalez, R. Miranda, M. Salmeron, J.A. Verges, F. Yndurain, Phys. Rev. B 24 (1981) 3245; and T. Beier, H. Jahrreiss, D. Pescia, Th. Woike, W. Gudat, Phys. Rev. B 61 (1988) 1875.
5. To be compared with Ref. [4]: A. Schmid, Growth of epitaxial Co thin films on Cu(100) studied by STM, Thesis FU Berlin, 1991; J. de la Figuera, J.E. Prieto, C. Ocal, R. Miranda, Phys. Rev. B 47 (1993) 13043. On both orientations (100) and (111) the growth of a high density of islands is observed.
