GeP
GeP is a thermodynamically stable semiconducting compound formed from germanium and phosphorus.
About GeP
GeP is a binary semiconducting material composed of germanium and phosphorus. As a thermodynamically stable phase residing on the convex hull, it represents a robust crystalline arrangement that is highly favored under standard conditions.
Its electronic character makes it a subject of significant interest for researchers investigating new semiconductor architectures. With a substantial number of reported structures across various databases, it serves as a key reference point for understanding the phase space of germanium-phosphorus systems.
Key Properties
Cross-validated computational properties for GeP, aggregated across 5 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of GeP. Tight agreement means computed properties can be trusted without re-running calculations.
