| Abstract: | An atomic model of growth with pairwise interactions is presented. By assuming coherent deposition the system is mapped onto a lattice-gas model. This leads to additional cluster interactions due to the lattice size mismatch between the substrate and the adsorbates. A numerical simulation with cluster interactions up to 5-body is performed. A narrow-size distribution of the nanostructures is obtained, as frequently observed experimentally. The computations show the possibility of explaining these distributions within the framework of the theory of Priester, C. and Lannoo, M., 1995, Phys. Rev. Lett., 75, 93. |
