CrSc2Tl
CrSc2Tl is a semimetallic ternary intermetallic compound containing chromium, scandium, and thallium.
About CrSc2Tl
CrSc2Tl is a complex ternary intermetallic compound composed of chromium, scandium, and thallium. Its electronic character is defined as a near-zero-gap semimetal, placing it in a unique position between metallic conductors and semiconducting materials.
While the compound has been documented across several structural databases, its thermodynamic profile indicates it resides above the stability hull. This suggests that while it can be synthesized or modeled in specific configurations, it may be inherently metastable under ambient conditions.
Key Properties
Cross-validated computational properties for CrSc2Tl, 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.
