Discovery and Control of Nanoscale Antipolar Phase

Scientific Achievement: Tomographic imaging discovered a new antipolar phase in van der Waals layered CuInP2S6.

Significance and Impact: This discovery provides insights into developing novel ferroic states, e. g. antiferroelectrics (AFE) for efficient and neuromorphic computing.
