Özet

© S. S. Ragimov, I. N. Askerzade, and G. I. Agaeva, 2021.For the first time, studies of the temperature dependences of the thermoelectric power for various composi-tions of Bi2Sr2CaxZn1-xCu2O8+y (x = 1; 0.8; 0.4) in the range 77-320 K have been carried out. The obtained ex-perimental results are analyzed within the framework of the Xin's two-band model. The concentration of holes per copper atom and the band gap of the semiconductor type Bi-O layers are determined. It is shown that the re-placement of the calcium element with zinc in these proportions does not lead to a change in the electronic band structure of Bi2Sr2CaCu2O8+y.
