The growth of entirely synthetic two-dimensional (2D) materials could further expand the library of naturally occurring layered solids and provide opportunities to design materials with finely tunable properties. Among them, the synthesis of elemental 2D materials is of particular interest as they represent the chemically simplest case and serve as model system for exploring the on-surface synthesis mechanism. Here, a pure atomically-thin blue phosphorous (BlueP) monolayer is synthesized via silicon intercalation of the BlueP-Au alloy on Au(111). The intercalation process is characterized at the atomic scale by low-temperature scanning probe microscopy, and further corroborated by synchrotron radiation-based x-ray photoelectron spectroscopy measurements. The evolution of the band structures from BlueP-Au alloy into Si intercalated BlueP are clearly revealed by angle-resolved photoemission spectroscopy and further verified by density functional theory calculations.

硅插层法合成单层蓝磷

完全合成的二维（2D）材料的增长可能会进一步扩展天然分层固体的库，并为设计具有可微调特性的材料提供机会。其中，元素二维材料的合成特别受关注，因为它们代表化学上最简单的情况，并充当探索表面合成机理的模型系统。在这里，通过在Au（111）上插入BlueP-Au合金的硅，合成了纯原子薄的蓝色磷（BlueP）单层。通过低温扫描探针显微镜在原子尺度上对插层过程进行了表征，并通过基于同步加速器辐射的X射线光电子能谱测量进一步证实了该过程。
