K3Li
K3Li is a metastable metallic compound consisting of potassium and lithium that exhibits significant structural diversity.
About K3Li
K3Li is a binary metallic compound formed from potassium and lithium. As a metallic system, it lacks an electronic band gap, reflecting its conductive nature and potential interest in studies of alkali metal alloys. The material is characterized by a significant degree of structural diversity, with numerous reported configurations across various databases. Its thermodynamic status as being above the hull suggests it is a metastable phase, which is a common feature for specific compositions in alkali metal systems that require precise synthesis conditions to stabilize. This complexity makes it a compelling subject for researchers investigating the limits of phase stability in simple metal alloys.
Key Properties
Cross-validated computational properties for K3Li, aggregated across 5 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.
