    摘要:

    采用成熟工藝制備了N型、P型調(diào)制摻雜型Si80Ge20基固溶體合金及等化學(xué)計(jì)量比的均勻摻雜型Si80Ge20基固溶體合金，重點(diǎn)研究了兩類固溶體合金的熱電性能。結(jié)果表明：溫度為773 K時(shí)，N型系列、P型系列，調(diào)制摻雜型固溶體合金較均勻摻雜型的功率因子分別提高了13.6%和49.2%，熱電優(yōu)值ZT分別提高了7.9%和12.9%

    Abstract:

    N-type, P-type modulation-doped Si80Ge20 solid solution alloy and equivalent stoichiometric ratio uniform-doped Si80Ge20 solid solution alloy were prepared by our mature technologies. We concentrated on the thermoelectric properties of both alloy materials. The results show that the power factors of N-type, P-type modulation-doped solid solution alloys are enhanced by 13.6% and 49.2% respectively, compared with that of uniform-doped Si80Ge20 solid solution alloy. And their ZT (thermoelectric figure of merit) are enhanced by 7.9% and 12.9%, respectively
