For the first time, studies of the temperature dependences of the thermoelectric power for various compositions of Bi₂Sr₂Ca_xZn_1−xCu₂O_8+y (x = 1; 0.8; 0.4) in the range 77–320 K have been carried out. The obtained experimental 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 replacement of the calcium element with zinc in these proportions does not lead to a change in the electronic band structure of Bi₂Sr₂CaCu₂O_8+y.

首次研究了在 77-320 K范围内Bi ₂ Sr ₂ Ca _x Zn _{1- x} Cu ₂ O _{8+ y} （x = 1; 0.8; 0.4）的各种成分对热电的温度依赖性已经进行了。在Xin的两波段模型的框架内分析了获得的实验结果。确定每个铜原子的空穴浓度和半导体型Bi-O层的带隙。结果表明，以这些比例用锌代替钙元素不会导致Bi ₂ Sr ₂ CaCu ₂ O的电子能带结构发生变化。_{8 + y}。
