Highlights
Composition-dependent charge transport and temperature-dependent density of state effective mass-dependent Seebeck coefficient were investigated in Bi2−xSbxTe3 (x = 1.56-1.68) compounds
High-temperature Hall measurements revealed that the charge transport in the compounds was governed dominantly by phonon scattering and influenced by alloy scattering depending on the amount of Sb
Contrary effects of Sb content on the Seebeck coefficient were discussed in terms of carrier concentration and density of state effective mass, and it was elucidated by temperature-normalized Pisarenko plot for the first time
Summary
Composition-dependent charge transport and temperature-dependent density of state effective mass-dependent Seebeck coefficient were investigated in Bi2−xSbxTe3 (x = 1.56-1.68) compounds.
