Effect of Dopant on N-Type Bi2Te2.7Se0.3 Thermoelectric Materials Fabricated by Spark Plasma Sintering

摘要：

　　The n-type Bi2Te2.7Se0.3 compounds were fabricated to investigate the characterization of spark plasma sintering with various SbI3 dopant contents.The Bi2Te2.7Se0.3 compounds with SbI3 dopant content is exhibited n-type conduction characterization,but the Bi2Te2.7Se0.3 compounds without SbI3 dopant content is exhibited p-type conduction characterization.The maximum Seebeck coeficient represented with 0.05wt.% SbI3 dopant content.The Seebeck coefficient of the sintered sample with increasing sintering temperature is increased from-158 to-182 μV/K.The electrical resistivity and thermal conductivity with 0.05wt.% SbI3 dopant content were 1.0 Ωm and 1.33 W/mK,respectively.
