ErMnO3
erbium manganite
ErMnO3 is a thermodynamically stable semiconducting oxide utilized in the field of oxygen-evolution catalysis.
About erbium manganite
ErMnO3 is a semiconducting oxide that sits on the convex hull, indicating its high thermodynamic stability. As a member of the rare-earth manganite family, it is frequently investigated for its potential in electrochemical energy conversion processes.
This material is particularly relevant for oxygen-evolution catalysis, where its electronic structure facilitates the necessary surface reactions. Its stability and structural versatility make it a compelling candidate for researchers seeking alternatives to traditional transition metal oxide catalysts.
Key Properties
Cross-validated computational properties for erbium manganite, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
