CaSbO2
CaSbO2 is a metastable, semiconducting ternary oxide containing calcium, antimony, and oxygen.
About CaSbO2
CaSbO2 is a complex ternary oxide composed of calcium, antimony, and oxygen. As a semiconducting material, it exhibits electronic properties that make it a subject of interest for fundamental solid-state studies and potential optoelectronic applications.
Because this compound is classified as metastable, it represents a synthetic challenge that requires precise control over processing conditions. Its existence in multiple reported structural configurations highlights the structural flexibility inherent in this specific elemental combination.
Key Properties
Cross-validated computational properties for CaSbO2, aggregated across 2 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.
