CdHgLa2
CdHgLa2 is a semimetallic intermetallic compound containing cadmium, mercury, and lanthanum that is considered potentially synthesizable.
About CdHgLa2
CdHgLa2 is a complex intermetallic compound composed of cadmium, mercury, and lanthanum. Its electronic structure is characterized as a near-zero-gap semimetal, placing it in a unique regime where conduction and valence bands meet, which is often of interest for studying exotic electronic phenomena.
Positioned near the thermodynamic hull, this material is considered a viable candidate for experimental synthesis. Given its presence in multiple structural databases, it represents a significant subject for researchers investigating the interplay of heavy elements and rare-earth components in solid-state chemistry.
Key Properties
Cross-validated computational properties for CdHgLa2, aggregated across 3 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.
