利用固相烧结法制备了Cd1-xMnxO(x=0、0.1％、0.3％、0.5％、0.7％)多晶块体样品并研究了Mn4+掺杂对CdO多晶高温电、热输运性能的影响.实验发现,随着Mn4+掺杂量的增加,样品的载流子浓度和迁移率同时增大,导致其电阻率降低、塞贝克系数变大;Mn4+掺杂虽然可以降低CdO的声子热导率κp,但因为电子热导率κe的大幅上升从而使样品的总热导率κ升高.本研究结果为CdO热电性能的进一步调控及优化提供了基础.“,”Cd1-x Mnx O(x =0,0.1％,0.3 ％,0.5 ％,0.7 ％) ceramics were synthesized by the conventional solid state reaction method and its electric and thermal transport were both studied.With the increasing of Mn4+-doping,both the carrier concentration and the mobility of Cd1-x Mnx O measured at room temperature increase,which leads to the significant decrease of the resistivity and increase of Seebeck coefficient S.In spite of the Mn4+-doping can effectively reduce the phonon thermal conductivity,the total thermal conductivity increases due to the electronic thermal conductivity increase with growing Mn4+-doping.
