Abstract: 

A simple two dimensional model of thin film growth based on the ballestic aggregation of hard disks is proposed. In this model the impinging hard disks travel in straight line and initially "stick" to the first previously deposited hard disk they contact. Previously (Dirks and Leamy (1977)) (1) the criterion for relaxation has been migration of the impinging disk to the nearest pocket formed by two additional disks. In this model, however, relaxation is dependent on the surrounding geometry of the previously deposited atoms. The deposited disk may "relax" into a position where it then contact three, two or one previously deposited disk(s). Zone I region which is mainly influenced by shadowing effects with limited adatoms diffusion is simulated. The influence of deposition rate, self-shadowing effect, substrate roughness including amorphous substrates were investigated. Results are in good agreement with the Structure Zone Model (SZM) predictions for thin metallic films.
