Abstract: Cd1-xMnxO(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-xMnxO 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.

Key words: CdO, Mn4+doping, electric transport, thermal transport
