en: Measurement of Seebeck coefficient and conductive behaviors of Bi2Te3xSex (x = 0.15-0.6) thermoelectric semiconductors without harmful dopants

en: A system for measuring Seebeck coefficient was constructed and applied to Bi2Te3-xSex (x = 0.15-0.6) samples without harmful dopants, prepared by mechanical alloying (MA) followed by hot pressing (HP). The constructed thermal contact method system, using single and multiple ΔT values, gave Seebeck coefficients of a standard reference material (SRM 3451) at room temperature confirmable as -230 ± 4 and -232 ± 1 µV/K, respectively. X-ray diffraction patterns and differential scanning calorimetry curves showed that the MA-HP-sintered samples of Bi2Te3-xSex were single-phase Bi2(Te,Se)3-related materials. All the Bi2Te3-xSex samples were n-type semiconductors. The maximum power factor was 1.4 × 10-3 W m-1 K-2 for Bi2Te2.8Se0.2 sintered at 623 K. These results indicated that doping with harmful materials of Bi2Te3-xSex compounds prepared by the MA-HP process is not necessary for carrier control.
