dc.description.abstract | Bi-doped n-type PbTe powders were fabricated by mechanical alloying and melting/grinding to compare the thermoelectric properties of the alloys with powder processing methods. Hot pressing of the PbTe powders was conducted at 650 degrees C and 750 degrees C for 1 hour in vacuum. When measured at temperatures ranging from 25 degrees C to 450 degrees C, PbTe fabricated by mechanical alloying exhibited more negative Seebeck coefficient, higher electrical resistivity and lower thermal conductivity, compared to ones prepared by melting/grinding. The temperature for the maximum figure-of-merit shifted to lower temperature for the specimens fabricated by mechanical alloying. When hot pressed at 650 degrees C, 0.3 wt% Bi-doped PbTe fabricated by mechanical alloying and melting/grinding exhibited a maximum figure-of-merit of 1.33x10(-3)/K at 200 degrees C and 1.07x10(-3)/K at 350 degrees C, respectively. | - |
