Research Abstract

Cluster deposited film's features are influenced by the production method of cluster during the flight path, the relevant physical scale to be studied is as large as centimeters. Moreover, since the behavior of segregation processes on the substrate is not negligible, the smallest physical scale is of the order of 10 nm. Although a complete analysis of this multiscale problem is extremely difficult, it provides a typical research subject in the dynamics of a complex system consisting of interacting subsystems with very different scales. In this paper a new model of cluster growth and deposition processes based on a combination of Direct Simulation Monte Carlo (DSMC) and Monte Carlo (MC) methods is introduced to examine the effects of experimental conditions on cluster growth and deposition processes. From the macroscopic viewpoint, we simulate the behavior of clusters and inert gas in the flight path under different experimental conditions. Several types of size distributions of generated clusters under various conditions are obtained by the present model. Moreover, the deposition process of these clusters is calculated by a simple model to estimate a morphologies of this nanostructures obtained by cluster deposition. In this model we assume that the deposited clusters are composed of two elements and segregation of deposited clusters occurred from energy gaps between two immiscible elements. The results of the simulations reveal that the size distribution is strongly related to the experimental conditions and in turn has a major effect on the film properties.
