TiNiSb is a ternary intermetallic compound combining titanium, nickel, and antimony, belonging to the half-Heusler family of semiconductors. This material is primarily of research interest for thermoelectric applications, where it can convert temperature gradients directly into electrical current or vice versa, making it a candidate for waste heat recovery and solid-state cooling systems. TiNiSb is notable for its tunable electronic and thermal properties within the half-Heusler family, offering potential advantages in high-temperature thermoelectric performance compared to conventional binary semiconductors, though it remains largely in the development phase for commercial adoption.
