Ga2Ge2N2Sr4
Ga2Ge2N2Sr4 is a thermodynamically stable, semimetallic quaternary nitride compound containing gallium, germanium, nitrogen, and strontium.
About Ga2Ge2N2Sr4
Ga2Ge2N2Sr4 is a complex quaternary nitride composed of gallium, germanium, nitrogen, and strontium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these elements that maintains integrity under standard conditions. Its electronic character is defined as near-zero-gap, placing it in the category of semimetallic materials. This electronic profile suggests unique charge transport behaviors that distinguish it from traditional wide-gap insulating nitrides. While it remains a specialized research material, its stability makes it a significant subject for exploring the intersection of group 13 and 14 elements within a nitrogen-rich framework.
Key Properties
Cross-validated computational properties for Ga2Ge2N2Sr4, 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.
