Cl32Te8
Cl32Te8 is a thermodynamically stable, wide-gap insulating compound containing tellurium and chlorine.
About Cl32Te8
Cl32Te8 is a distinct inorganic compound composed of chlorine and tellurium. As a thermodynamically stable material situated on the convex hull, it represents a well-defined structural arrangement within its chemical system. Its electronic character is defined by a wide band gap, classifying it as an insulator with limited electrical conductivity under standard conditions. The existence of multiple reported structures across databases highlights its structural complexity and interest for solid-state research. This compound serves as a fundamental subject for understanding the bonding and stability of tellurium-based halides. Its insulating nature makes it a candidate for specialized applications where non-conductive, stable inorganic phases are required.
Key Properties
Cross-validated computational properties for Cl32Te8, aggregated across 4 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.
