二维（2D）层状材料在纳米电子学、柔性器件、可持续能源和催化剂等各个领域的基础研究和器件应用都受到了极大的关注。迫切需要对二维材料的结构和性能进行精确的表征。拉曼散射光谱具有方便、快速、无创等优点，是目前最流行的表征工具之一。从声子模式的频率和电子共振拉曼散射的强度两方面提供了晶格结构的信息。虽然一些形态表征工具可以以原子分辨率对二维材料进行成像，但拉曼散射测量对样品制备条件（如衬底）的耐受性更强，技术要求更低，并且已成为表征二维材料的常规工具之一。在这篇综述中，我们着重于利用拉曼散射光谱来表征二维材料，特别是揭示与原始二维材料的不同之处，如缺陷、掺杂效应、范德华异质结构和与分子的相互作用。本文将讨论这种差异的特征拉曼特征及其解释。希望本文能对材料、物理、化学和工程等领域的研究有所帮助。
Two-dimensional (2D) layered materials have attracted tremendous attention and led to a prosperous development in both fundamental investigation and device applications in various fields, such as nanoelectronics, flexible devices, sustainable energy and catalysts. The precise characterization of the structure and properties of 2D materials is in urgent need. Raman scattering spectroscopy is one of the most popular characterization tools that is convenient, rapid and non-invasive. It provides information on both the lattice structure from the frequency of phonon modes and the electronic band structure through the intensity due to electronic resonance Raman scattering. Although a few morphological characterization tools can image 2D materials with atomic resolution, Raman scattering measurements are more tolerant to the conditions of sample preparation such as the substrate and less technically demanding, and have been one of the routine tools for the characterization of 2D materials. In this review, we focus on the characterization of 2D materials using Raman scattering spectroscopy, in particular, the revealing of differences from primitive 2D materials, such as defects, doping effects, van der Waals heterostructures and the interaction with molecules. The characteristic Raman features of such differences and the corresponding interpretation will be discussed. We hope that this review will be useful for wide research communities of materials, physics, chemistry and engineering.
