We provide a computational study of a change in the morphology of a growing thin film during condensation caused by electromigration effects. It will be shown, that separated circular adsorbate islands, realized in an isotropic system, become elongated in the direction of the applied electrical field. We discuss the dependence of the critical value of the strength of the applied electrical field, responsible for the formation of percolating adsorbate islands, on main control parameters. This study provides insight into details of electromigration effects during the self-organization of adatoms into percolating adsorbate islands during condensation from the gaseous phase. We will show that the elongated morphology of adsorbate islands remains stable if the electric field is turned off.
我们对电迁移效应导致的冷凝过程中生长薄膜形态变化进行了计算研究。结果表明，在各向同性系统中形成的分离圆形吸附质岛，会在施加电场的方向上伸长。我们讨论了导致渗流吸附质岛形成的外加电场强度临界值与主要控制参数之间的依赖关系。这项研究深入了解了气相冷凝过程中吸附原子自组织形成渗流吸附质岛时电迁移效应的细节。我们将表明，如果关闭电场，吸附质岛的伸长形态将保持稳定。
