Surface morphology of a modified ballistic deposition model
arXiv:1311.2182 · doi:10.1103/PhysRevE.90.022111
Abstract
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.
