CsTe
CsTe is a stable semiconducting binary compound formed from cesium and tellurium.

About CsTe
CsTe is a binary semiconducting material composed of cesium and tellurium. As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration of these elements that maintains structural integrity under standard conditions.
Its importance in materials research is underscored by the high volume of structural data available for this composition. This extensive characterization highlights its complex nature and potential utility in fundamental electronic studies where precise control over stoichiometry and phase stability is required.
Key Properties
Cross-validated computational properties for CsTe, 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.
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.
