CaLi2Sr
CaLi2Sr is a semiconducting ternary intermetallic compound that is thermodynamically unstable.
About CaLi2Sr
CaLi2Sr is a ternary intermetallic compound composed of calcium, lithium, and strontium. It exhibits semiconducting electronic behavior, marking it as a subject of interest for researchers investigating the interplay between alkaline earth metals and alkali metals in solid-state structures. Due to its position above the thermodynamic hull, this material is considered likely unstable under standard conditions. Despite this, it remains a notable entry in structural databases, with multiple reported configurations that provide insight into the complex bonding environments possible for this combination of elements.
Key Properties
Cross-validated computational properties for CaLi2Sr, 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.
