SrLi2Nb2O7
SrLi2Nb2O7 is a semiconducting mixed-metal oxide that is theoretically stable enough to be synthesized for experimental study.
About SrLi2Nb2O7
SrLi2Nb2O7 is a complex oxide composed of strontium, lithium, niobium, and oxygen. Its electronic character as a semiconductor makes it an intriguing subject for investigation in solid-state chemistry and materials science.
Because it is classified as a near-hull material, it is considered thermodynamically accessible for experimental synthesis. The presence of multiple reported structures across databases suggests a rich structural landscape that warrants further exploration for potential functional properties.
Key Properties
Cross-validated computational properties for SrLi2Nb2O7, 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.
