论文摘要
硅烯是一种新的二维（2D）材料，由于无处不在的现代技术中使用了硅。但是，事实证明，生产独立硅的硅胶是一个巨大的挑战。到目前为止，只能在金属表面上合成硅烷，在金属表面自然形成与金属底物变化其电子特性的强烈相互作用。在这里，我们报告了在绝缘NaCl薄膜上的第一个实验证据。这项工作代表了一个重大突破。为了研究硅烯的固有特性，并扩展到迄今为止仅在金属表面上生长的其他2D材料。
Silicene, a new two-dimensional (2D) material has attracted intense research because of the ubiquitous use of silicon in modern technology. However, producing free-standing silicene has proved to be a huge challenge. Until now, silicene could be synthesized only on metal surfaces where it naturally forms strong interactions with the metal substrate that modify its electronic properties. Here, we report the first experimental evidence of silicene sheet on an insulating NaCl thin film. This work represents a major breakthrough; for the study of the intrinsic properties of silicene, and by extension to other 2D materials that have so far only been grown on metal surfaces.
