KBiO3
KBiO3 is a thermodynamically stable semiconducting oxide composed of potassium, bismuth, and oxygen.
About KBiO3
KBiO3 is a semiconducting oxide that sits firmly on the convex hull, indicating it is a thermodynamically stable phase. Its composition of potassium, bismuth, and oxygen positions it as a subject of interest for researchers investigating complex oxide systems with stable structural frameworks. The material has been documented with multiple distinct structural configurations across major databases, reflecting its versatility in solid-state chemistry. This structural diversity makes it a compelling candidate for studies focused on electronic properties and phase stability. As a stable semiconductor, it offers a reliable platform for exploring the interplay between heavy metal cations and oxygen coordination in crystalline lattices.
Key Properties
Cross-validated computational properties for KBiO3, 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.
