(color online) (a) Room-temperature Hall carrier concentration and Hall mobility of Mg_3−xLi_xSb₂ (x = 0, 0.005, 0.01, 0.02), (b) the Seebeck coefficient versus carrier concentration at room temperature. The black solid curve is the calculated relation between Seebeck coefficient and carrier concentration using an SPB model with m*=0.76me , while the scatters represent the experimental data of Mg_3−xLi_xSb₂ (x = 0, 0.005, 0.01, 0.02) compounds.
