GeAs
GeAs is a stable semiconducting material formed from germanium and arsenic that is widely documented in structural databases.
About GeAs
GeAs is a semiconducting binary compound composed of germanium and arsenic. As a thermodynamically stable phase located on the convex hull, it represents a robust structural configuration that has attracted significant interest in materials science research.
With extensive documentation across multiple databases, this material serves as a key subject for understanding the interplay between group 14 and group 15 elements. Its electronic character makes it a candidate for specialized semiconductor applications where stability and specific structural arrangements are required.
Key Properties
Cross-validated computational properties for GeAs, 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.
