At monolayer coverage, silicene on Ag(1 1 1) may present different structural phases depending on the growth conditions. At multilayer coverage, only one structural phase has been reported: the [Formula: see text] phase. However, no link between the structural arrangement of the monolayer and that of the multilayer has been addressed. In this paper, reporting experimental work based on low-energy electron diffraction and scanning tunneling microscopy, we focus on the structural aspects of a multilayer film of silicene. We demonstrate that it exhibits one structural arrangement, namely the [Formula: see text] form, but with different domain orientations resulting from the structural properties of the initial wetting monolayer.
在单层覆盖时，Ag(1 1 1) 上的硅烯可能会根据生长条件呈现不同的结构相。在多层覆盖时，仅报道了一种结构相：[公式：见正文] 相。然而，单层和多层的结构排列之间的联系尚未得到探讨。在本文中，我们基于低能电子衍射和扫描隧道显微镜报告实验工作，重点关注硅烯多层膜的结构方面。我们证明它呈现一种结构排列，即 [公式：见正文] 形式，但由于初始润湿单层的结构特性导致具有不同的畴取向。
