Two-dimensional (2D) layered materials have received much attention due to the unique properties stemming from their van der Waals (vdW) interactions, quantum confinement, and many-body interactions of quasi-particles, which drive their exotic optical and electronic properties, making them critical in many applications. Here, we review our past years' findings, focusing on many-body interactions in 2D layered materials, including phonon anharmonicity, electron-phonon coupling (), exciton dynamics, and phonon anisotropy based on temperature (polarization)-dependent Raman spectroscopy and Photoluminescence (PL). Our review sheds light on the role of quasi-particles in tuning the material properties, which could help optimize 2D materials for future applications in electronic and optoelectronic devices.
二维（2D）层状材料因其源自范德华（vdW）相互作用、量子限制以及准粒子的多体相互作用的独特性质而备受关注，这些性质驱动了它们奇异的光学和电子特性，使其在许多应用中至关重要。在此，我们回顾过去几年的研究成果，重点关注二维层状材料中的多体相互作用，包括声子非简谐性、电子 - 声子耦合（）、激子动力学以及基于温度（偏振）相关拉曼光谱和光致发光（PL）的声子各向异性。我们的综述揭示了准粒子在调节材料性质中的作用，这有助于优化二维材料，以用于未来电子和光电器件的应用。
