Figure 5. (A)Density of states effective mass as a function of temperature for the Mg1.95Si0.233Sn0.7Sb0.067-II sample. The effective mass was obtained from room temperature Hall measurement, assuming a constant carrier concentration; (B) Weighted mobility (μw) and Hall mobility (μH) of Mg2.06Si0.385Sn0.6Sb0.015 and Mg1.95Si0.233Sn0.7Sb0.067-II.
