Amorphous single-stage crystallization process

Once a continues layer of the film is formed, (often referred to, as a monolayer), further film growth is a reenactment of the nucleation-growth processes occurring under steady state conditions. During this stage, the film evolves into any of, amorphous, polycrystalline or single crystal forms, depending on several parameters such as substrate temperature, nature of the film deposited, and so on.
