AsSe
AsSe is a thermodynamically stable semiconducting compound formed from arsenic and selenium.
About AsSe
AsSe is a binary inorganic compound composed of arsenic and selenium. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration of these elements that maintains structural integrity under standard conditions.
This material exhibits semiconducting electronic properties, making it a subject of interest for fundamental studies in solid-state physics. With a significant number of reported structures across major databases, it serves as a versatile model for understanding bonding and structural polymorphism in chalcogenide systems.
Key Properties
Cross-validated computational properties for AsSe, 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.
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.
