磷是一种重要的非金属元素，具有许多同素异形体和可调谐的电子特性。作为磷最重要的同素异形体之一，二维（2D）黑磷（BP）具有许多非凡的性质，如高载流子迁移率和高开/关比，厚度相关的直接带隙从0.3到2ev不等，以及各向异性的电学、光学和热性质。受2D BP成功的启发，其他具有有趣性质的用于下一代电子和光电子器件的2D磷同素异形体也引起了人们的关注。然而，大规模生长高质量的二维单层/多层磷仍然是一个巨大的挑战。在这篇综述中，我们强调了最近在二维磷方面取得的进展，特别关注二维BP膜、蓝磷（BlueP）单层以及磷-金属多孔网络的外延生长。最后指出了单层磷或磷金属合金的发展面临的挑战和未来的发展前景。
Phosphorus is an important non‐metal element with many allotropes and tunable electronic properties. As one of the most important allotropes of phosphorus, two‐dimensional (2D) black phosphorus (BP) possesses many extraordinary properties, such as high charge carrier mobility with high on/off ratio, thickness‐dependent direct bandgap varying from 0.3 to 2 eV, and anisotropic electrical, optical and thermal properties. Inspiring by the success of 2D BP, other 2D phosphorus allotropes with intriguing properties for next‐generation electronic and optoelectronic devices have also attracted much attention. However, large‐scale growth of high‐quality 2D single/few‐layer phosphorus remains a great challenge. In this review, we highlight recent progress achieved on 2D phosphorus, with special focus on the epitaxial growth of 2D BP films, blue phosphorus (BlueP) monolayers as well as phosphorus‐metal porous networks. The remaining challenges and future perspectives on the development of monolayer phosphorus or phosphorus‐metal alloys are also provided.
