| 摘 要： | 含遮蔽抛射沉积模型是在抛射沉积(BD)模型的基础上考虑了粒子以一定的角度分布倾斜入射的情况.本文应用外推方法确定了大尺寸极限下含遮蔽抛射沉积模型的各标度指数,讨论了该模型的有限尺寸效应及其标度性质.从模拟结果可以看出含遮蔽BD模型的有限尺寸效应与BD模型有所不同,遮蔽这种非局域作用可以显著地改变BD模型的标度性质.

| Abstract: | The model of ballistic deposition (BD) with shadowing means that the tilt incidence of particles in a certain angle of distribution is taken into account based on the BD model. In this paper,in order to investigate the finite size effect and the scaling properties of the BD with shadowing,the extrapolation method is used to determine the asymptotic scaling exponents of the model in the large-size limit. The simulation results illustrate that the finite size effect on BD with shadowing is different from that on BD, and the shadowing as a nonlocal interation can significantly change the scaling properties of BD model. |
