Ga1In1Li2
Ga1In1Li2 is an unstable, semimetallic ternary alloy composed of gallium, indium, and lithium.
About Ga1In1Li2
Ga1In1Li2 is a ternary intermetallic compound composed of gallium, indium, and lithium. Its electronic character is defined by a near-zero band gap, placing it in the category of semimetallic materials that exhibit complex electronic behavior due to the interplay of its constituent elements.
As a material that resides above the thermodynamic convex hull, Ga1In1Li2 is considered metastable or unstable under standard conditions. Despite this, it remains a subject of significant interest in computational materials science, with numerous structural configurations identified that provide insight into the phase space of lithium-rich alloys.
Key Properties
Cross-validated computational properties for Ga1In1Li2, aggregated across 2 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.
