AsSeI
AsSeI is a stable, semiconducting ternary compound consisting of arsenic, selenium, and iodine.
About AsSeI
AsSeI is a distinct ternary compound composed of arsenic, selenium, and iodine. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions.
This material exhibits semiconducting electronic behavior, making it an interesting candidate for specialized optoelectronic or sensing applications. Its multi-element composition allows for complex bonding environments that are characteristic of chalcogenide-halide systems.
Key Properties
Cross-validated computational properties for AsSeI, 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.
