摘要:

我们报道了二维Si/Au(110)表面合金形成的实验证据。在这项研究中,我们使用了扫描隧道显微镜,低能电子衍射,俄歇电子能谱和从头计算的基础上密度泛函理论的组合。在保持高于共晶温度的Au(110)衬底上生长硅的亚单层之后,观察到高度有序和稳定的Si-Au表面合金。

英文摘要:

We report on experimental evidence for the formation of a two dimensional Si/Au(110) surface alloy. In this study, we have used a combination of scanning tunneling microscopy, low energy electron diffraction, Auger electron spectroscopy and ab initio calculations based on density functional theory. A highly ordered and stable Si-Au surface alloy is observed subsequent to growth of a sub-monolayer of silicon on an Au(110) substrate kept above the eutectic temperature.
