Observation of an intermediate state during lithium intercalation of twisted bilayer MoS₂.

ABSTRACT: Lithium intercalation of MoS₂ is generally believed to introduce a phase transition from H phase (semiconducting) to T phase (metallic). However, during the intercalation process, a spatially sharp boundary is usually formed between the fully intercalated T phase MoS₂ and non-intercalated H phase MoS₂. The intermediate state, i.e., lightly intercalated H phase MoS₂ without a phase transition, is difficult to investigate by optical-microscope-based spectroscopy due to the narrow size. Here, we report the stabilization of the intermediate state across the whole flake of twisted bilayer MoS₂. The twisted bilayer system allows the lithium to intercalate from the top surface and enables fast Li-ion diffusion by the reduced interlayer intera
