Zr₀.₅Hf₀.₅NiSn₁.₉₉₄Sb₀.₀₀₆ is a half-Heusler intermetallic compound combining zirconium, hafnium, nickel, and tin with trace antimony doping. This is a research-phase thermoelectric material designed to convert waste heat into electrical power through the Seebeck effect, with the dual-element Zr/Hf substitution and Sb doping used to optimize phonon scattering and electronic transport for improved energy conversion efficiency. The material belongs to a family of half-Heusler thermoelectrics being investigated for mid-to-high temperature energy harvesting applications where conventional thermal management is impractical.
