Elucidation of adsorbat-aedsorbate interactions in surface diffusion

在本研究中，我们利用原子跟踪扫描隧道显微镜（STM）研究了分子在金属表面的扩散过程中ad - o_2 - o_2 - trebate的相互作用。我们还开发了一个蒙特罗模拟程序，包括吸附物-吸附物相互作用，以阐明先前报道的异常较小尝试频率的来源。我们改进了我们的原子跟踪STM软件。通过我们的模拟，我们还发现，随着Au原子接近其他Au原子时感受到的额外扩散屏障的增加，Au岛的数量也增加了。

In the present study, we investigated ads-oardbsaotrebate interactions in surface diffusion of Amuonomers on metallic surfacebsy using atom trackisncganning tunneling microscopy (STM). We also developed a MonterloCasimulation program including the adsorbate-adsorbate interaction to elucidate the origin of anomalously smaller attempt frequencies reported previously. Wiemproved our atom tracking STM soft.warBey our simulation, we also found that the Au islansditydenincreasedwith increasing the additional diffusion barrier that Au atoms feel when they approach other Au atoms.
