MoS₂ is a layered material that has attracted attention as a new device material that can replace existing materials such as semiconductors and electrodes for ion batteries. In recent studies, lattice relaxation, which is a phenomenon unique to layered materials, has been reported to change the layer structure by intercalation. We have measured Na-intercalated single crystal MoS₂ and attempted to analyze the 3D atomic arrangement of Na. In this presentation, we will report the layer structure change and the existence site of Na by comparing with the calculation.
