About CaMg5
CaMg5 is a metastable intermetallic compound composed of calcium and magnesium. As a semiconducting material, it represents a specialized niche in binary alloy systems, drawing interest for its distinct electronic behavior and structural complexity. Its formation is characterized by a delicate balance of atomic interactions that result in a metastable state under ambient conditions. Researchers study this compound to understand the fundamental physics governing its electronic properties and the structural arrangements that emerge within the calcium-magnesium phase space. Given the significant number of reported structural variations, it serves as a compelling subject for those investigating phase stability and crystal engineering in metal-rich systems.
Key Properties
Cross-validated computational properties for CaMg5, 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.
