Al1La1Li2
Al1La1Li2 is a semimetallic, thermodynamically metastable ternary compound composed of aluminum, lanthanum, and lithium.
About Al1La1Li2
Al1La1Li2 is a complex ternary intermetallic compound composed of aluminum, lanthanum, and lithium. Its electronic character is defined as near-zero-gap, placing it in the semimetallic regime where conduction properties are highly sensitive to structural configuration.
Despite the existence of numerous reported structural variations for this composition, the material is considered thermodynamically unstable relative to its constituent elements. This instability suggests that while it can be synthesized under specific conditions, it remains a challenging subject for long-term material integration.
Key Properties
