HoSb
HoSb is a stable metallic compound consisting of holmium and antimony that is frequently studied for its fundamental electronic and structural properties.
About HoSb
HoSb is a metallic compound formed from the rare-earth element holmium and the metalloid antimony. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of these two elements. Its metallic nature suggests high electrical conductivity, making it an interesting subject for studies in solid-state physics and materials science. The compound is well-documented in structural databases, reflecting its significance in fundamental research. Researchers often investigate such binary intermetallic compounds to understand the interplay between rare-earth magnetism and electronic transport properties. Its stability ensures that it maintains its integrity under standard conditions, facilitating its use as a reliable model system for exploring complex electronic behaviors.
Key Properties
Cross-validated computational properties for HoSb, aggregated across 6 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 HoSb. Tight agreement means computed properties can be trusted without re-running calculations.
