Intercalation-Induced Phase Transitions in Ferroelectric α-In₂Se₃.

ABSTRACT: Specific ions can be intercalated into functional materials using the electrolyte gating technique, which has been widely used to regulate channel conductance in transistors and develop low-power neuromorphic devices. However, in these devices, fundamental exploration of ion intercalation-induced structural phase transitions remains largely overlooked and rarely explored. Here, the lithium-based electrolyte gating technique is used to probe the collective interactions between ions, lattices, and electrons in a van der Waals ferroelectric semiconductor α-In₂Se₃. Using a polymer electrolyte as the lithium-ion reservoir and α-In₂Se₃ as the channel material, the intercalated lithium concentration via a gate electric field is modulated. This manipulat
