  In this work we investigate influence of substrate temperature on the surface
morphology for substrate coverage below one monolayer. The model of film growth
is based on random deposition enriched by limited surface diffusion. Also
anisotropy in the growth is involved. We found from computer simulations for
simple cubic lattice and solid-on-solid model, that the surface morphology
changes with increasing temperature from isotropically distributed isolated
small islands, through anisotropic 1-D stripes to larger 2-D anisotropic
islands and again randomly distributed single atoms. The transition is also
marked in height-height correlation function dependence on temperature, as
directly seen by snapshots from simulations. The results are in good
qualitative agreement with already published results of kinetic Monte Carlo
simulations, as well as with some experimental data.
