A model for the polycrystalline growth of materials on an amorphous substrate, in the submonolayer regime, is introduced and studied by means of Monte Carlo simulations. Starting from an initial density of nucleation centers (0), all crystals grow up incorporating particles at perimeter sites. Due to the formation of intercrystalline gaps, the saturation coverage decreases monotonically when 0 is increased. The time evolution of growing sites and the crystal size distribution are analyzed and discussed in detail. Scaling approaches for those quantities are derived and tested with the Monte Carlo data.
