Enhancing Thermoelectric Performance of GeTe through Sb Doping and SiC Nanocomposite for Reduced Thermal Conductivity

A combined strategy of aliovalent doping and compositing engineering was conducted in GeTe to minimize the thermal conductivity for boosting thermoelectric properties, with a zT max of 1.82 achieved for Ge 0.92 Sb 0.08 Te + 0.2 wt% SiC at 800 K.
