一种改进的弹道沉积模型的表面形貌

Surface morphology of a modified ballistic deposition model

Kasturi Banerjee, J. Shamanna, Subhankar Ray

摘要:

研究了改进的弹道沉积模型的表面和体相性质。沉积规则在最近和次最近邻弹道沉积和随机沉积模型之间插值。沉积颗粒的粘性由参数和颗粒间力的类型控制。两个这样的力量被认为是库仑和范德华类型。在最终饱和之前,界面宽度显示出三个不同的生长区域。增长率更强烈地依赖于粘性参数比颗粒间力的类型。然而,沉积物的孔隙率强烈地受颗粒间力的影响。

英文摘要:

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.
