Two-dimensional (2D) blue phosphorene with a honeycomb structure is the phosphorus analog of graphene, and is regarded as a promising 2D material with a large tunable band gap and high charge-carrier mobility. Here, using the molecular beam epitaxy method, we synthesize monolayer blue phosphorene on the Ag(111) surface. Combined with first-principles calculations, scanning tunneling microscopy measurements reveal that the blue phosphorene on the Ag(111) surface consists of 2D clusters with a buckling 1 × 1 lattice, arranged regularly on the Ag(111). The formation of these phosphorus clusters stems from the strain modulation induced by the lattice mismatch between blue phosphorene and the Ag(111) substrate. Moreover, x-ray photoelectron spectroscopy measurements are performed to study the instability of the blue phosphorene clusters in air. The realization of regular nanoclusters of blue phosphorene with unique sizes and morphology provides an ideal platform for the exploration o...

Ag（111）上蓝色磷的二维簇的规则排列

具有蜂窝结构的二维（2D）蓝色磷光体是石墨烯的磷类似物，被认为是一种有前途的2D材料，具有可调谐的带隙大和高的载流子迁移率。在这里，我们使用分子束外延方法，在Ag（111）表面上合成了单层蓝色磷光体。结合第一性原理计算，扫描隧道显微镜测量结果表明，Ag（111）表面上的蓝色磷光体由规则排列在Ag（111）上的具有1×1晶格的2D簇组成。这些磷簇的形成源于蓝色磷光体与Ag（111）衬底之间晶格失配引起的应变调制。此外，进行X射线光电子能谱测量以研究空气中蓝色磷簇的不稳定性。
