Cu1Ga1Ti2
Cu1Ga1Ti2 is a semimetallic Heusler alloy that exists as a metastable phase within a large family of titanium-based intermetallic compounds.
About Cu1Ga1Ti2
Cu1Ga1Ti2 is a complex intermetallic compound belonging to the class of Heusler alloys. It exhibits a near-zero-gap electronic character, placing it in the category of semimetallic materials that often bridge the gap between conductive metals and semiconducting solids.
While this material has been identified across multiple structural configurations, it is characterized as being thermodynamically unstable relative to the ground state. Its existence as a metastable phase provides valuable insights into the formation energy landscapes of ternary and quaternary titanium-based systems.
Key Properties
