MgMn3SnO8
MgMn3SnO8 is a semiconducting complex oxide composed of magnesium, manganese, tin, and oxygen.
About MgMn3SnO8
MgMn3SnO8 is a complex oxide containing magnesium, manganese, and tin. As a semiconducting material, it exhibits electronic properties that distinguish it from simple binary oxides, making it a subject of interest for fundamental solid-state studies.
While this compound is currently identified as being above the thermodynamic hull, its existence across multiple structural configurations suggests a complex energy landscape. It serves as an intriguing example of multi-cation oxide chemistry where structural diversity is a key focus of investigation.
Key Properties
Cross-validated computational properties for MgMn3SnO8, aggregated across 2 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.
