· Hf3 Au1

Hf3Au1 is an intermetallic compound combining hafnium and gold in a 3:1 stoichiometric ratio, classified as a semiconductor material. This is a research-phase compound within the hafnium-gold system, explored primarily for its electronic and structural properties rather than as a production material. The hafnium-gold family is of interest in advanced electronics and high-temperature applications where intermetallic phases offer tunable band gaps and enhanced thermal stability compared to conventional semiconductors.
