Er8Te12
Er8Te12 is a stable semimetallic binary compound formed from erbium and tellurium.
About Er8Te12
Er8Te12 is a binary inorganic compound composed of erbium and tellurium. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement within the rare-earth chalcogenide family. Its electronic character is defined as near-zero-gap, placing it in the semimetallic regime where conduction properties are highly sensitive to its specific atomic configuration.
This material is notable for its structural diversity, supported by multiple reported entries across major materials databases. Its stability and electronic nature make it a subject of interest for researchers investigating the fundamental interactions between rare-earth elements and chalcogens in complex crystalline lattices.
Key Properties
Cross-validated computational properties for Er8Te12, 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.
