HW3
HW3 is a metallic hydrogen-tungsten compound known for its structural complexity and metastable nature.
About HW3
HW3 is a binary metallic compound composed of hydrogen and tungsten. As a metallic system, it exhibits conductive electronic behavior, reflecting the interaction between the transition metal and the light element within its lattice structure. The compound is characterized by a significant degree of structural diversity, as evidenced by the numerous reported configurations across multiple databases. Its position relative to the thermodynamic ground state suggests that it is a metastable phase, which remains a subject of interest for fundamental materials exploration.
Key Properties
Cross-validated computational properties for HW3, 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.
