△ [15p-E206-14] Thermoelectric properties of V, Fe co-substituted MnSiγ synthesized by melt-grown method

Keywords:thermoelectric materials, higher manganese silicides, V, Fe co-substitution

Higher manganese silicides (HMSs) are known as good thermoelectric (TE) materials because of their low cost, less-toxicity and high chemical stability. Recently, we synthesized V-substituted HMSs by melt-grown method, and succeeded in enhancing TE properties owing to the increase of hole carrier density and dissipation of MnSi layered precipitates in HMSs. The aim of this study is to further increase TE properties by V, Fe co-substitution.
