CeMg5
CeMg5 is a metastable, semiconducting intermetallic compound formed from cerium and magnesium.
About CeMg5
CeMg5 is a distinct intermetallic compound composed of cerium and magnesium. As a metastable phase, it represents a complex structural arrangement that highlights the intricate bonding interactions between rare-earth elements and alkaline earth metals.
This material is characterized by its semiconducting electronic nature, distinguishing it from typical metallic alloys. Its existence within a broad landscape of structural variations underscores the sensitivity of its formation to specific synthesis conditions.
Key Properties
Cross-validated computational properties for CeMg5, 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.
