| Abstract [eng] |
Due to the importance of thin films in modern high technologies, it is important to know their physical parameters and be able to predict them. Surface roughness is one of the important, experimentally measurable, parameters that partly defines the structure of the coating and other structure related physical parameters. Predicting roughness and its associated physical parameters facilitates the work of researchers because there is no need to actually grow and study materials that are often expensive and difficult to create. Experimentally, other authors found that, surface roughness varies nonlinearly with temperature. By choosing an already existing mathematical model of surface growth, graphs of temperature dependence of roughness were modeled. After studying the selected range of diffusion parameters, the areas of decrease and increase of surface roughness with changing temperature-dependent diffusion parameters were determined. The coverage features of individual monolayers with changing temperature and its parameters were investigated. |
