SrAs
SrAs is a thermodynamically stable semimetallic compound containing strontium and arsenic.

About SrAs
SrAs is a binary inorganic compound composed of strontium and arsenic. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within its chemical system, supported by a significant body of structural data across multiple databases. Its electronic character is defined as near-zero-gap, placing it in the category of semimetallic materials. This electronic profile makes it a subject of interest for researchers investigating materials with unique charge carrier dynamics. While its specific applications are still emerging, its stability and electronic nature position it as a key candidate for fundamental studies in condensed matter physics.
Key Properties
Cross-validated computational properties for SrAs, 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.
