Thermoelectric Properties on n-Type Bi_xSb_(1-x)/Bi_2Te_3 Graded Materials Containing Fullerite or Carbon Tube

摘要

Bi_xSb_(1-x) and Bi_2Te_3 are typical thermoelectric materials used for lower temperature. Samples of Graded materials containing different amount of fullerite or nanometer carbon tube and the were fabricated by hot pressing method. The relations about thermoelectric property, the addition of fullerite or nanometer carbon tube, and the microstructure were investigated in detail by normal measurement or analytical method.
