Ho2O8V2
Ho2O8V2 is a stable, semiconducting holmium vanadate compound used in materials research.
About Ho2O8V2
Ho2O8V2 is a complex holmium-based vanadate that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement within the holmium-vanadium-oxygen system. This stability makes it a significant subject for researchers investigating the interplay between rare-earth elements and transition metal oxides.
Because of its well-defined structural characteristics and reported occurrences across multiple databases, this compound serves as a valuable reference point for solid-state chemistry. Its electronic profile suggests potential utility in specialized electronic or optical applications where stable semiconducting oxides are required.
Key Properties
Cross-validated computational properties for Ho2O8V2, aggregated across 3 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.
