About HfMo
HfMo is a binary metallic compound formed from the transition metals hafnium and molybdenum. As a metallic system, it exhibits characteristic electronic behavior associated with its d-block constituents, reflecting a complex interplay between the atomic structures of its parent elements.
Despite its metallic nature, this compound is identified as being above the thermodynamic hull, suggesting it is inherently unstable under standard conditions. Its existence is documented through a significant number of reported structural variations across multiple databases, highlighting its role as a subject of interest in structural research.
Key Properties
Cross-validated computational properties for HfMo, 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.
