Ferroelectric 2D antimony oxides with wide bandgaps

Abstract

Two 2D polymorphs of antimony dioxide, γ-Sb2O4 and δ-Sb2O4, are predicted using the evolutionary algorithm and first-principles calculations. Out-of-plane ferroelectricity is found in γ-Sb2O4, while in-plane ferroelectricity is found in δ-Sb2O4.
