The application of two-dimensional (2D) materials, including metallic graphene, semiconducting transition metal dichalcogenides, and insulating hexagonal boron nitride (h-BN) for surface-enhancement Raman spectroscopy has attracted extensive research interest. This article provides a critical overview of the recent developments in surface-enhanced Raman spectroscopy using 2D materials. By re-examining the relationship between the lattice structure and Raman enhancement characteristics, including vibration selectivity and thickness dependence, we highlight the important role of dipoles in the chemical enhancement of 2D materials.
二维（2D）材料，包括金属石墨烯、半导体过渡金属二硫属化物和绝缘六方氮化硼（h-BN）在表面增强拉曼光谱中的应用已引起广泛的研究兴趣。本文对使用二维材料的表面增强拉曼光谱的最新进展进行了批判性综述。通过重新审视晶格结构与拉曼增强特性之间的关系，包括振动选择性和厚度依赖性，我们强调了偶极子在二维材料化学增强中的重要作用。
