About Cd1Y2Zn1
Cd1Y2Zn1 is a complex intermetallic compound composed of cadmium, yttrium, and zinc. It exhibits a near-zero-gap electronic character, placing it in the category of semimetallic materials that bridge the gap between conductors and insulators.
Due to its position above the thermodynamic hull, this compound is considered metastable, making it a subject of significant interest for researchers studying phase stability and structural diversity. Its existence across multiple reported structures highlights the intricate bonding behaviors present in ternary transition metal systems.
Key Properties
