Ferroelectricity in wurtzite-structured materials has been discovered in a variety of systems since the report by Fichtner et al. in 2019. In ZnO, ferroelectricity has been reported to emerge through Mg substitution and Ce-Mn co-substitution, and in recent years its switching behavior has been actively studied. We have fabricated ZCM epitaxial thin films on Si substrates and reported a low coercive field of about 1.5 MV/cm. In this presentation, we carried out a detailed analysis of the switching characteristics and related properties of this material.
