(color online) The Se content-dependent data points of (a) nH, (b) determined η, (c) determined md , and (d) determined Edef. The nH-dependent data points of (e) μH, and (f) S compared with the theoretical curves of μH versus nH, and S versus nH calculated with the correspondingly determined Edef, and md . In all figures, the solid green data points are from Bi2Te3−xSex ingots doped with I (wt 0.08%),[123] the hollow red data points are from Bi2Te3−xSex processed by BM+HP+HD,[100] and the hollow blue data points are from Bi2Te3−xSex single crystals.[121]
