Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

ABSTRACT Precise modulation of ferroelectric properties in van der Waals (vdW) layered materials is crucial for multifunctional nanoelectronics. Here, we demonstrate that Li⁺ substitution at Cu sites (Cu1‐xLixInP2S6, x≤ 0.1) concurrently enhances ferroelectric and ionic conductivities, and enriches...
