ScNiSb
semiconductor· ScNiSb
ScNiSb is a ternary intermetallic compound combining scandium, nickel, and antimony, belonging to the Heusler or half-Heusler alloy family of semiconductors. This material is primarily of research interest for thermoelectric and spintronic applications, where its electronic band structure and thermal transport properties make it a candidate for solid-state energy conversion and potential magnetoresistive devices. The compound represents an emerging materials system where engineers and materials scientists explore unconventional elemental combinations to achieve improved figure-of-merit values or novel functional properties beyond what conventional binary or ternary semiconductors provide.
