About PrTe2
PrTe2 is a metallic compound composed of praseodymium 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.
This material is of significant interest in condensed matter physics due to its metallic electronic character. Its presence across multiple structural databases highlights its importance as a subject for experimental and computational study in the field of rare-earth chalcogenides.
Key Properties
Cross-validated computational properties for PrTe2, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
