摘要：

The high temperature conductivity of the 2212 phase of Bi-Sr-Ca-Cu-O superconductors was determined as a function of temperature and oxygen partial pressure. The dependences of conductivity on temperature T and oxygen partial pressure P(O2) were similar to those of oxygen content, and two subphases, alpha and beta, were found as the case of oxygen content. From these results a close relationship between the conductivity and the oxygen content was concluded, and the morbility and carrier density were calculated by assuming that one oxygen atom creates two mobile electron holes. It was found that both mobility and carrier density were close to those obtained by the measurements of Hall coefficient and conductivity below room temperature.
