Semi-Heusler / Heusler alloys with tailor-made phase separation

摘要

It is an inorganic, intermetallic compound, characterized in that the compound contains at least two elements per formula unit and consist of at least 2 phases, at least one phase being semiconducting or semi-metallic, these at least two phases being immiscible and thermodynamically stable. The invention allows the thermal conductivity of half-Heusler alloys to be reduced while at the same time maintaining the electrical conductivity and the thermal voltage.
