About Cs2Te3
Cs2Te3 is a binary telluride compound that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of cesium and tellurium atoms. This stability suggests a well-defined crystalline framework that is favorable for fundamental materials research.
Given its electronic nature, this compound is of interest for studies involving chalcogenide-based semiconductors. Its existence as a distinct, stable phase allows researchers to investigate the interplay between alkali metal cations and tellurium networks, providing insights into the broader chemistry of binary tellurides.
Key Properties
Cross-validated computational properties for Cs2Te3, aggregated across 2 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.
