“…Although the buckling height found are in a good agreement with the theoretical and experimental results available in the literature, one must be careful in comparing values across different works in this subject. It is widely recognized that silicene can adopt different structures depending on the substrate and temperature conditions [19]. The majority of studies have utilized Ag as the substrate or even no substrate at all (investigating free-standing silicene).…”

“…The characterization of silicene is a complex task, not only due to the necessity of different analysis approach (including scanning tunneling microscopy, angleresolved photoemission spectroscopy, and first principles calculations) but also because the interpretation of these results can be greatly influenced by the substrate [18]. Besides, the structures obtained can assume numerous metastable configurations depending on the substrate temperature and flux of depositing Si atoms [19]. As a result, many experimental results are still under debate.…”

Despite the remarkable theoretical applications of silicene, its synthesis remains a complex task, with epitaxial growth being one of the main routes involving depositing evaporated Si atoms onto a suitable substrate. Additionally, the requirement for a substrate to maintain the silicene stability poses several difficulties in accurately determining the growth mechanisms and the resulting structures, leading to conflicting results in the literature. In this study, large-scale molecular dynamics simulations are performed to uncover the growth mechanisms and characteristics of epitaxially grown silicene sheets on Au(111) and Au(110) substrates, considering different temperatures and Si deposition rates. The growth process has been found to initiate with the nucleation of several independent islands homogeneously distributed on the substrate surface, which gradually merge to form a complete silicene sheet. The results consistently demonstrate the presence of a buckled silicene structure, although this characteristic is notably reduced when using an Au(111) substrate. Furthermore, the analysis also focuses on the quality and growth mode of the silicene sheets, considering the influence of temperature and deposition rate. The findings reveal a prevalence of the Frank-vander Merwe growth mode, along with diverse forms of defects throughout the sheets.

After more than ten years since the silicene discovery, many Xenes, the class of elemental graphene-like lattices, have now enriched the two-dimensional periodic table of elements. Here, we provide a perspective on the future of the Xenes by briefly summarizing their properties and devices reported thus far. Two main challenges are expected to focus the scientists’ attention to bring the Xenes to the next level. To step over the current scenario the Xenes need standardization either in the growth or in the fabrication of devices, aiming at the wafer-scale and the reliability and stability, respectively. The benefits arising from these challenges will enable the concept of hybrid Xenes and hybrid Xenes-based devices, that is a combination of different Xenes with new properties and multifunctional Xenes-based devices, respectively, with potential unexpected fascinating properties to continue the journey.
