Introduction Thermoelectric material, one of the most promising energy materials, has received more attention recently, since the engineering thermoelectric devices have been widely applied in the conversion of waste heat to electric energy as well as in solid-state Peltier cooling [1-3].
In engineering thermoelectric materials, bismuth telluride is usually made as n- or p-type thermal elements in thermal devices [4], and its figure of merit ZT is near unity, where ZT=α2σT/κ is the characteristic performance of thermoelectric materials and the parameters of α, σ, κ, and T are Seebeck coefficient, electrical conductivity, thermal conductivity, and Kelvin temperature, respectively.
Besides, the parameter of α2σ named Power Factor (PF) expresses the comprehensive electric properties of thermoelectric materials.
