Abstract: Abstract Quaternary Mg2Si0.25Ge0.05Sn0.7 based solid solutions were synthesized by B2O3 flux method combined with spark plasma sintering (SPS) technique. The carrier concentration was tuned by adjustment of the SPS temperature. The electrical conductivity, Seebeck coefficient… read more here.
