AbstractCrystal phase plays a crucial role in determining the properties of two-dimensional (2D) transition metal dichalcogenides. Here we achieve phase-switchable preparation of 2D transition metal dichalcogenides using an electrochemical lithium-ion intercalation-based exfoliation strategy by controlling the discharge current density and cutoff voltage.

Two-dimensional (2D) magnets with tunable ferromagnetic resonance (a phenomenon where the magnetization in a magnetic material resonates with an external electromagnetic field) and spin waves (fluctuation caused by the magnetic interaction between magnetic atoms) are gaining attention for energy-efficient electronics due to their lightweight and low-dimensional nature.

Intercalation is a powerful tool for inducing phase changes in transition metal dichalcogenides (TMDs). However, only the transition from a semiconducting 2H (hexagonal) phase to metallic 1T (octahedral, or semi-metallic 1T′, distorted octahedral) phase induced by lithium ion (Li+) intercalation in MoS2 is well-known, due to its versatile chemistry and rich physics with adjustable electronic and optical properties.
