Patterns and scaling properties in a ballistic deposition model

We study a ballistic deposition model in 1+1 dimensions in which the incident angles (the angles between the incident trajectories and the substrate) of incoming particles and randomly distributed in the range [{θ},{π}-{θ}]. We find a sharp morphological transition at a critical angle θc{}10 ^∘{}. For {θ}>θc, the scaling properties of the interface are described by the Kardar-Parisi-Zhang equation. For {θ}θc, the shadowing effect leads to a very different morphology. We determine the scaling properties of this new universality class numerically and analytically.
