    • V1 and Vis are slightly different, owed to the different relaxation taking place in the island configuration and in the WL. Both volumes can be estimated as V= V0 (1+Trε ), where ε is the strain tensor (in the island or in the WL) and V0 is the reference (Ge bulk) volume. While all theoretical results reported in the figures were obtained by considering such correction, for the rather shallow islands here considered we verified that setting V1 = Vis =V is a good approximation. For sake of simplicity, therefore, results are (safely) discussed in terms of a common V value.

    • Calculations in Ref. are carried out up to N=5, showing a tendency toward convergence but not a true limiting value. While in the present paper vales above N=5 are not relevant, we have extended our calculations up to N=6, imposing full convergence of the surface energy at the N=5 value to better emphasize the thick-film limit.

    • In our model we simply compare pyramids, domes, and wetting layer. Indefinite dome enlargement in a real system would be opposed by several effects (kinetic limitations, further shape transformation, deep trenches formation and SiGe intermixing, dislocation nucleation, island-island elastic repulsion, etc.) not considered in our treatment, only aimed at understanding the first stages of growth.
