我们通过拉曼散射研究了多层MoS 2中的剪切模式和层呼吸模式。这些都是通过偏振测量和对称性分析确定的。它们的位置随着层数的变化而变化，奇数层和偶数层的缩放比例不同。一个链模型可以解释的结果，具有普遍适用性的任何层状材料，允许其厚度的可靠诊断。© 2013美国物理学会.
We study by Raman scattering the shear and layer breathing modes in multilayer MoS2. These are identified by polarization measurements and symmetry analysis. Their positions change significantly with the number of layers, with different scaling for odd and even layers. A chain model can explain the results, with general applicability to any layered material, allowing a reliable diagnostic of their thickness. © 2013 American Physical Society.
