| 蓝磷烯因其多种独特性质而在自旋电子器件和光电器件等领域受到越来越多的关注. 通过分子束外延技术已成功在Au(111)基底上构筑了单层蓝磷烯结构. 蓝磷烯的一个显著特性是其随层数可调的带隙,因此,实现蓝磷烯的可控合成对于深入理解其物理化学性质以及光电领域的潜在应用具有重要意义. 然而,目前对于蓝磷烯在Au(111)基底上外延生长的动力学机制及相关特性尚未得到充分理解. 本文结合俄歇电子能谱、低能电子衍射和扫描隧道显微技术,研究了磷原子在Au(111)基底上的生长行为. 研究发现,在低覆盖率下,蓝磷烯开始成核并快速生长,并形成相对于Au(111) (1 × 1)具有(5 × 5)的超晶格结构. 蓝磷烯在Au(111)基底上的形态在很大程度上取决于生长温度,而覆盖率的影响很小,显示出蓝磷烯在Au(111)基底上的自限制生长行为,阻碍了其在Au(111)表面形成多层磷烯结构. 该研究对进一步理解蓝磷烯的外延生长机理具有重要意义. |

| Blue phosphorene has recently attracted increasing attention owing to its distinctive properties. The synthesis of a monolayer blue phosphorene has been realized by molecular-beam epitaxy (MBE) on an Au(111) substrate. One of the remarkable characteristics of blue phosphorene is its tunable bandgap, which depends on the number of layers. Therefore, achieving the controlled synthesis of blue phosphorene is of critical importance for a deeper understanding of its physicochemical properties and its potential applications in optoelectronics. However, the growth dynamics and related properties of blue phosphorene on an Au(111) substrate remain insufficiently understood. Here, we employ Auger electron spectroscopy, low-energy electron diffraction, and scanning tunneling microscopy to investigate the growth behavior of phosphorus atoms on an Au(111) substrate. The results indicate that at low coverage, blue phosphorene nucleates and grows rapidly, forming a monolayer structure characterized by a (5 × 5) reconstruction relative to the Au(111) (1 × 1) surface. The morphology of blue phosphorene on the Au(111) substrate is predominantly influenced by growth temperature, while the effect of coverage is minimal. This suggests that blue phosphorene exhibits self-limiting growth on the Au(111) substrate, thereby preventing the formation of multilayer phosphorene structures. These findings provide valuable insights into the epitaxial growth mechanisms of blue phosphorene. |
