Query: Surface morphology of a modified ballistic deposition model   The surface and bulk properties of a modified ballistic deposition model are
investigated. The deposition rule interpolates between nearest and next-nearest
neighbor ballistic deposition and the random deposition models. The stickiness
of the depositing particle is controlled by a parameter and the type of
inter-particle force. Two such forces are considered - Coulomb and van der
Waals type. The interface width shows three distinct growth regions before
eventual saturation. The rate of growth depends more strongly on the stickiness
parameter than on the type of inter-particle force. However, the porosity of
the deposits is strongly influenced by the inter-particle force.
