Boosting the thermoelectric performance of GeTe by manipulating the phase transition temperature <i>via</i> Sb doping
Yang Jin, Dongyang Wang, Yuting Qiu, Li‐Dong Zhao
Abstract
With rising Sb content, the crystal symmetry of Sb-doped GeTe elevates by lowing phase transition temperature, thus leading to superior thermoelectric properties. A <italic>ZT</italic><sub>max</sub> of ∼1.8 at 773 K and <italic>ZT</italic><sub>ave</sub> of ∼1.1 can be obtained in Ge<sub>0.9</sub>Sb<sub>0.1</sub>Te.
