Al1Cu1Y2
Al1Cu1Y2 is a semiconducting ternary intermetallic compound containing aluminum, copper, and yttrium.
About Al1Cu1Y2
Al1Cu1Y2 is a ternary intermetallic compound composed of aluminum, copper, and yttrium. It exhibits semiconducting electronic characteristics, distinguishing it from typical metallic alloys in this chemical space.
Due to its position above the thermodynamic hull, this material is considered metastable. It remains a subject of interest for researchers studying complex phase stability and the structural diversity of rare-earth-containing intermetallics.
Key Properties
Cross-validated computational properties for Al1Cu1Y2, aggregated across 2 databases.
