Ca3In3N5
Ca3In3N5 is a complex, metastable ternary nitride semiconductor composed of calcium, indium, and nitrogen.
About Ca3In3N5
Ca3In3N5 is a complex ternary nitride semiconductor that incorporates calcium and indium into a nitrogen-based framework. As a member of the diverse nitride semiconductor class, it represents an interesting, albeit structurally intricate, arrangement of elements that deviates from simpler binary configurations.
Due to its position relative to the thermodynamic hull, this compound is considered metastable, which presents unique challenges and opportunities for synthetic materials science. Its electronic character positions it as a subject of interest for researchers investigating the tunable properties of multi-component nitrides.
Key Properties
Cross-validated computational properties for Ca3In3N5, 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.

How It Compares
Within the nitride semiconductors class.
Unlike the highly stable and industrially ubiquitous binary nitrides such as GaN or InN, Ca3In3N5 exhibits a more complex stoichiometry that places it in a different regime of thermodynamic stability. While materials like BN and AlN are prized for their robust, simple crystalline lattices, Ca3In3N5 represents a more exotic, data-rich experimental target that highlights the structural variety possible within the nitride semiconductor family.
