Ge2W
Ge2W is a metallic, metastable compound formed from tungsten and germanium that is frequently studied for its complex structural properties.
About Ge2W
Ge2W is a metallic intermetallic compound composed of germanium and tungsten. As a metastable phase, it represents a complex structural arrangement that exists within the broader landscape of transition metal germanides, characterized by its lack of a band gap and distinct electronic behavior.
This material is of significant interest in condensed matter physics and materials research due to the high number of reported structural configurations. Its metallic nature and specific stoichiometry make it a subject of study for understanding phase stability and bonding interactions in binary metal-germanium systems.
Key Properties
Cross-validated computational properties for Ge2W, 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.
