Local symmetry-driven interfacial magnetization and electronic states in (ZnO)_n/(w-FeO)_n superlattices

Abstract

Superlattices constructed with the wide-band-gap semiconductor ZnO and magnetic oxide FeO, both in the wurtzite structure, have been investigated using spin-polarized first-principles calculations.

Interfacial electronic state between hexagonal ZnO and cubic NiO

“…33 Recent theoretical work has shown the presence of two interfaces driven by local symmetry in the (ZnO) n /(w-FeO) n superlattices. 33 If such interesting local-symmetry-induced interfaces can be realized experimentally, the model proposed in this work will be well-suited for examining interface properties. With the advancement of characterization techniques, 25,34–37 and the development of materials informatics and machine learning, 38 the combination of our proposed model and big data in materials science may contribute to the in-depth study of interfaces.…”
