About zinc arsenide
Zn3As2 is a semiconducting compound composed of zinc and arsenic. It is recognized for its thermodynamic stability, sitting directly on the convex hull, which makes it a robust candidate for materials science research and device development. The compound exhibits significant structural diversity, with numerous reported configurations across major databases. This structural flexibility underscores its importance as a versatile platform for exploring electronic phenomena in binary pnictides. Its semiconducting nature allows for precise tuning of charge carrier properties, which is essential for developing high-performance electronic components. As a stable material, it offers a reliable foundation for thin-film deposition and integration into complex heterostructures.
Key Properties
Cross-validated computational properties for zinc arsenide, 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.
