CrMg30O32Zn
CrMg30O32Zn is a semiconducting oxide compound that is considered a viable candidate for experimental synthesis.
About CrMg30O32Zn
CrMg30O32Zn is a complex oxide containing chromium, magnesium, oxygen, and zinc. Its electronic character is defined as semiconducting, positioning it as an interesting subject for materials research where specific charge transport properties are required.
Because this material is identified as near-hull, it is considered likely synthesizable under controlled laboratory conditions. The existence of multiple reported structures across databases highlights its significance as a target for further structural and functional investigation.
Key Properties
Cross-validated computational properties for CrMg30O32Zn, aggregated across 3 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
