Several phenomena can affect the phonon bands of low‐dimensional systems, and their proper assignment and interpretation are essential in elucidating their effect on electronic, optical, and optoelectronic properties. Using an analytical approach, we investigate the similarities and differences of the layered effect, the phonon confinement effect, the Breit–Wigner–Fano effect, the inhomogeneous heating effect, and disorder‐induced effects in the phonon line shapes of WS₂ and MoS₂. The subtle differences and similarities are critical in making proper assignments and interpretations of the phonon line shapes and are useful as guidance in the behavior of phonon bands, particularly in TMDs, and more generally in low‐dimensional systems.

研究TMD的声子线形：一种分析方法

几种现象会影响低维系统的声子带，因此，对它们的正确分配和解释对于阐明其对电子，光学和光电特性的影响至关重要。使用一种分析方法，我们研究了WS ₂和MoS ₂声子线形中的分层效应，声子约束效应，Breit-Wigner-Fano效应，不均匀加热效应和无序诱发效应的异同。。细微的差异和相似之处对于正确分配和解释声子线形至关重要，对于指导声子带的行为（特别是在TMD中，尤其是在低维系统中）的行为很有用。
