· K2 Sn2 Sb2

K2Sn2Sb2 is an experimental ternary intermetallic semiconductor compound composed of potassium, tin, and antimony. While not yet established in mainstream engineering applications, materials in this chemical family are of research interest for thermoelectric energy conversion and solid-state electronics, where mixed-metal antimonides and stannides offer potential advantages in tailoring band structure and phonon scattering for improved performance compared to single-element or binary semiconductors.
