In 2D materials, the quantum confinement and van der Waals-type interlayer interactions largely govern the fundamental electronic and optical properties, and the dielectric screening plays a dominant role in the excitonic properties. This suggests strongly layer-dependent properties and a central topic is to characterize and control the interlayer interactions in 2D materials and heterostructures. Black phosphorus is an emerging 2D semiconductor with unusually strong interlayer interactions and widely tunable direct bandgaps from the monolayer to the bulk, offering an ideal platform to probe the layer-dependent properties and the crossover from 2D to 3D (i.e., the scaling effects). In this review, a comprehensive and thorough summary of the fundamental physical properties of black phosphorus is presented, with a special focus on the layer-dependence character, including the electronic band structures, optical absorption and photoluminescence, and excitonic properties, as well as the band structure engineering by means of electrical gating, strain, and electrochemical intercalation. Finally, an outlook is given for the future research.

二维黑磷的层相关电子和光学特性：基础和工程

在二维材料中，量子限制和范德华式层间相互作用在很大程度上决定了基本的电子和光学特性，介电屏蔽在激子特性中起主导作用。这表明强烈依赖于层的特性，中心主题是表征和控制二维材料和异质结构中的层间相互作用。黑磷是一种新兴的 2D 半导体，具有异常强的层间相互作用和从单层到块体的广泛可调的直接带隙，提供了一个理想的平台来探测层相关特性和从 2D 到 3D 的交叉（即缩放效应）。在这篇综述中，对黑磷的基本物理性质进行了全面而彻底的总结，特别关注层依赖性特征，包括电子能带结构、光吸收和光致发光、激子特性，以及通过电门控、应变和电化学插层的能带结构工程。最后，对未来的研究进行展望。
