Abstract— <p>The article discusses the deposition of a gas onto a crystalline substrate in the presence of a permeable membrane between the substrate and the gas. The membrane repels gas particles; however, the repulsive potential has a finite maximum force, thus allowing gas particles to penetrate through this membrane when their velocity exceeds a certain value. It is shown that, depending on the maximum repulsive force of the membrane (repulsion intensity), the system acquires absolutely different final states: a single crystal, polycrystals with different degrees of porosity, or no crystallization occurs in the system at all.</p>
