VPO5
VPO5 is a thermodynamically stable transition-metal phosphate semiconductor used in materials research.
About VPO5
VPO5 is a transition-metal phosphate that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust structural framework within the broader family of phosphate-based materials. The compound is characterized by significant structural diversity, supported by a wealth of reported data across multiple databases. Its stable nature and electronic properties make it a subject of interest for researchers investigating ion-conducting pathways and catalytic frameworks. The material serves as a foundational building block in the study of complex oxide systems, where the interplay between vanadium and phosphorus coordination environments dictates its functional utility.
Key Properties
Cross-validated computational properties for VPO5, 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.
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.

How It Compares
Within the transition-metal phosphates class.
Within the class of transition-metal phosphates, VPO5 occupies a distinct position compared to battery-relevant materials like LiFePO4 or LiMnPO4. While many of its siblings are primarily studied for their lithium-intercalation capabilities, VPO5 provides a different structural template that highlights the versatility of vanadium-based frameworks in contrast to the olivine-type structures seen in iron or cobalt phosphates.
