The thermal power and conductivity of superconducting Bi2Sr2Ca0,4Zn0,6Cu2Oу


The temperature dependence of the resistivity and thermoelectric power of bismuth Bi2Sr2Ca0,4Zn0,6Cu2Oу superconductor in the range 77-320K is carried out. The experimental results on thermoelectric power are analyzed within the framework of the Xin’s two-band model and the band gap of Bi-O layers is determined as Eg=0.059 eV.

Keywords: superconducting material, specific resistivity, thermal power.
