(a) Hall carrier measurement of Mg3+δSb2-yBiy solid solutions (, 1, 1.2, 1.4, and 1.6). (b) Bi content-dependent Hall mobility, theoretical and experimental data from literature as references [5, 7, 8, 18, 28, 35, 39]. (c) Comparison of Hall carrier concentration and mobility in this work and reference reported Mg3+δSb2-yBiy system [8, 3840]. (d) Weighted mobility and electron effective mass of Mg3+δSb2-yBiy-0.01Te0.01:Mn0.01 solid solutions ().
