AlLiTe2 is a thermodynamically stable semiconducting ternary compound consisting of aluminum, lithium, and tellurium.
About AlLiTe2
AlLiTe2 is a distinct ternary compound composed of aluminum, lithium, and tellurium. As a thermodynamically stable phase located on the convex hull, it represents a well-defined structural arrangement that suggests robust chemical stability under standard conditions. Its electronic character is defined as semiconducting, making it a subject of interest for researchers investigating new electronic and optoelectronic materials. The existence of multiple reported structures across various databases highlights its significance as a material with diverse crystallographic potential. By balancing its constituent elements, AlLiTe2 serves as a foundational example of complex chalcogenide systems that offer tunable properties for specialized technological applications.
Key Properties
Cross-validated computational properties for AlLiTe2, 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.
