Theoretical studies of the formation and growth of adsorbate surface structures during condensation from the gas phase are carried out within the framework of the reaction-diffusion model. By taking into account that the adsorbate concentration decreases from layer to layer, the influence of the diffusion coefficient of adatoms between layers on the average value of the adsorbate concentration on the first layer, the spatial ordering of the adsorbate, and the morphology of the surface layer is analysed. The obtained theoretical results are confirmed by independent numerical modelling.
Key words: condensation, thin films, adsorbate, structure formation, surface morphology.
