摘要：

This paper presents the results of the investigations on electrical conductivity and thermoelectric power of YBa2Cu3O7-y as a function of temperature (680-1170 K) and oxygen pressure (10(5)-30 Pa) at thermodynamic equilibrium. The analysis of electrical properties as a function of the deviation from stoichiometry allowed one to determine the type of dominating electronic defects and transport properties in different temperatures and nonstoichiometry. A qualitative model for the electronic structure of YBa2Cu3O7-y at high temperatures is proposed.
