Probing stacking configurations in a few layered MoS₂ by low frequency Raman spectroscopy.

ABSTRACT: Novel two-dimensional (2D) layered materials, such as MoS₂, have recently gained a significant traction, chiefly due to their tunable electronic and optical properties. A major attribute that affects the tunability is the number of layers in the system. Another important, but often overlooked aspect is the stacking configuration between the layers, which can modify their electro-optic properties through changes in internal symmetries and interlayer interactions. This demands a thorough understanding of interlayer stacking configurations of these materials before they can be used in devices. Here, we investigate the spatial distribution of various stacking configurations and variations in interlayer interactions in few-layered MoS₂ flakes probed through the low-frequen
