Hf1 Co1 Sb1
semiconductor· Hf1 Co1 Sb1
HfCoSb is an intermetallic compound combining hafnium, cobalt, and antimony in a 1:1:1 stoichiometry, belonging to the broader family of half-Heusler semiconductors. This is a research-phase material being investigated for thermoelectric applications where efficient conversion between thermal and electrical energy is critical, offering potential advantages over conventional thermoelectric materials in mid-to-high temperature regimes. The compound is notable within materials research for its potential to deliver improved figure-of-merit through optimized band structure and reduced thermal conductivity, though it remains primarily in academic and experimental development rather than established industrial production.
