自从2014年通过机械剥离成功制备二维（2D）黑磷（BP）以来，最近有相当多的研究集中在二维（2D）黑磷（BP）上。按比例缩小后，具有原子厚度的BP显示出迷人的半导体特性，具有层依赖的直接带隙和高载流子迁移率。制备高质量的少层BP薄膜对于研究其独特的晶体结构、基本特性以及在电子学、生物医学、储能、光子学和光电子学等领域的潜在应用至关重要。因此，本文综述了单层和少层BP主题的合成方法以外的剥离，包括减薄处理伴随着剥离，从赤磷到BP的转换，和直接生长技术。我们总结了在合成过程中控制BP样品厚度和横向尺寸的各种尝试。此外，我们讨论了目前的挑战和前景的大规模增长的BCPBP一直是一个瓶颈，阻碍了晶圆级器件的发展在这一领域。我们希望能为探索合成高质量BP薄膜的可行方法提供一个新的思路，以发展高性能的纳米电子学和光子学，这可能会加速二维BP向真实的应用的进展。
A considerable number of recent research have focused on two-dimensional (2D) black phosphorus (BP) since it was successfully prepared through mechanical exfoliation in 2014. After scaling down, BP with atomistic thickness shows fascinating semiconducting features with layer-dependent direct bandgap and high carrier mobility. The synthesis of high-quality few-layer BP thin films is critical to investigate their distinctive crystal structure, fundamental characteristics, as well as the potential applications in electronics, biomedicine, energy storage, photonics, and optoelectronics. Therefore, this review provides an overview of mono- and few-layer BP topic in the synthesis methods beyond exfoliation, including thinning treatments accompanied to exfoliation, conversion from red phosphorus to BP, and direct growth techniques. We summarize various attempts to control the BP sample's thickness and lateral dimensions during the synthesis. Furthermore, we discuss the current challenges and perspectives of large-scale growth of ultrathin BP which has been a bottleneck hindering wafer-scale device's development in this field. We hope to provide an insight into exploring some potential approaches practicable to synthesize high quality BP thin films utilized for developing high-performance nano-electronics and photonics, which may accelerate the progress of 2D BP toward real applications.
