Bi1–xSbx solid solutions are the best n-type thermoelectric materials for use at temperatures ≤200 K. An important parameter determining material’s figure of merit is charge carrier concentration. To determine it correctly, one should carry out

It was established that the dependences of thermoelectric and mechanical properties of cold-pressed Bi2(Te1−xSex)3 alloys on composition (x = 0–0.07) exhibit a non-monotonic behavior in certain concentration ranges: an anomalous decrease in the S

The room-temperature dependences of thermoelectric properties (the Seebeck coefficient S, the electrical conductivity σ, the Hall coefficient RH, and the thermoelectric power factor P = S2·σ) on the thickness (d = 5 - 250 nm) of the Bi0.98Sb0.02 s
