Abstract
In this work, we have conducted an NLS-based Monte-Carlo modeling and characterization for antiferroelectric/ferroelectric (AFE/FE) Hf 1- x Zr x O 2 (HZO). With the coexistence of orthorhombic-phase (FE) and tetragonal-phase (AFE) grains and the crucial consideration of back-switching field, our generalized NLS model is capable of describing the switching dynamics and frequency response of AFE/FE HZO. Our experimentally verified model is adequate for modeling HZO with certain AFE and FE properties, which can be beneficial to future memory applications and neuromorphic computing.
