采用成熟工艺制备了N型、P型调制掺杂型Si80Ge20基固溶体合金及等化学计量比的均匀掺杂型Si80Ge20基固溶体合金,重点研究了两类固溶体合金的热电性能。结果表明:温度为773 K时,N型系列、P型系列,调制掺杂型固溶体合金较均匀掺杂型的功率因子分别提高了13.6%和49.2%,热电优值ZT分别提高了7.9%和12.9%。 The N-type, P-type doped Si80Ge20-based solid solution alloys and the uniform stoichiometric Si80Ge20-based solid solution alloys were prepared by the mature technology. The thermoelectric properties of the two types of solid solution alloys were mainly studied. The results show that at 773 K, the power factor of the more uniform doped N-type, P-type and D-doped solid solution alloys are increased by 13.6% and 49.2%, respectively, and the thermal figure of merit ZT is increased by 7.9% and 12.9%.
