Effect of Bi-doping and Mg-excess on the thermoelectric properties of Mg2Si materials
(2014)In this work, Bi-doped magnesium silicide compounds were prepared by applying a combination of both, short-time ball milling and heating treatment. The effect of Mg excess was also studied, aiming towards further improvement ...
