Direct Observation of Electron Beam Induced Cu Ion Migration and Aggregation Dynamics in Van Der Waals Layered CuInP2S6
Researchers used in‑situ transmission electron microscopy and density‑functional theory to directly observe copper ion migration in the van der Waals ferroelectric CuInP2S6 (CIPS) under electron‑beam irradiation.
