Abstract: Effects of the ball-mill treatment of raw materials and the sintering temperature on PIES (Pulverized and Intermixed Element Sintering) process were investigated for preparation of non-doped Bi2Te3, Se-doped Bi2Tel._n-type) and Sb-doped Bi2Tel._p-type) elements. ふaresult, the power factor(P) strongly depended upon ball-mill treatment: P value for non-doped elements increased with an increase in ball-milling time , and in the case of doped-elements the maximum P values were obtained in 1 hour-milling for n-type and in 18-20 hours-milling for p-type elements. Our trial module consisted of a pair of elements with excellent P value showed a good cooling ability.
