AsCuSe2
AsCuSe2 is a semiconducting ternary compound of arsenic, copper, and selenium that demonstrates high structural complexity.
About AsCuSe2
AsCuSe2 is a ternary semiconducting material composed of arsenic, copper, and selenium. Its electronic properties make it a subject of interest for researchers exploring chalcogenide-based semiconductors and their potential roles in optoelectronic applications. While it exhibits significant structural complexity with numerous reported configurations, it is characterized as being thermodynamically above the hull. This suggests that while it can be synthesized in various forms, it remains a metastable phase that requires specific conditions for formation.
Key Properties
Cross-validated computational properties for AsCuSe2, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
