KTl
KTl is a metallic intermetallic compound formed from potassium and thallium that exhibits structural stability suitable for potential synthesis.
About KTl
KTl is a metallic intermetallic compound composed of potassium and thallium. Its electronic structure is characterized by a lack of a band gap, identifying it as a metallic conductor rather than a semiconductor or insulator.
The compound is considered near the thermodynamic hull, indicating that it is a viable candidate for experimental synthesis. With numerous reported structures across various databases, it remains a subject of interest for researchers studying the structural diversity of alkali-thallide systems.
Key Properties
Cross-validated computational properties for KTl, 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.
