    • A novel silicon-base thermoelectric transducing material containing a P- or N-type semiconductor obtained by adding various impurities to Si, which is produced with good productivity at low cost and has a stable quality and a high performance index. Generally when various elements are added to Si, the Seebeck coefficient of the material decreases with the carrier concentration until the carrier concentration exceeds 10 18 M/m 3 , and a minimum value of the Seebeck coefficient is in a range from 10 18 to 10 19 M/m 3 . The material of the invention is a P- or N-type semiconductor having a carrier concentration of 10 17 to 10 20 M/m 3 and containing Si and 0.001 to 0.5 atomic % of one or more elements of Be, Mg, Ca, Sr, Ba Zn, Cd, Hg, B, Al, Ga, In, and Tl, or one or more elements of N, P, As, Sb, Bi, O, S, Se, and Te, and another material is a P- or N-type semiconductor having a carrier concentration of 10 19 to 10 21 M/m 3 and containing Si and 0.5 to 10 atomic % of one or more of the elements.
    • 一种新颖的硅基热电转换材料,其含有通过向Si中添加各种杂质而获得的P-型或N型半导体,其以低成本生产且具有稳定的质量和高的性能指数。 通常当将各种元素添加到Si时,材料的塞贝克系数随着载流子浓度而降低,直到载流子浓度超过10 18 M / m 3,塞贝克系数的最小值在10 18至10 19 M / m 3。 本发明的材料是载流子浓度为10 17至10 20 M / m 3并含有Si和0.001至0.5原子%的一种或多种元素的P型或N型半导体 ,Mg,Ca,Sr,Ba Zn,Cd,Hg,B,Al,Ga,In和Tl,或N,P,As,Sb,Bi,O,S,Se和Te中的一种或多种元素, 另一种材料是载流子浓度为10 19至10 21 M / m 3并含有Si和0.5至10原子%的一种或多种元素的P-型或N型半导体。
