Relaxor Antiferroelectric Dynamics for Neuromorphic Computing.

Relaxor antiferroelectric (AFE) materials display a gradual polarization response and high energy storage density with polarization slowly reverting after removing an external field. This distinctive polarization-switching behavior closely resembles synaptic plasticity in biological nervous systems, presenting substantial potential for neuromorphic computing applications. Especially, its 2D scenario exhibits unique physical properties and maintains stability at atomic thickness due to their antipolar alignment, which effectively eliminates the depolarization field effect.
