摘要

研究了不同氧化帽层的1- uct (1- uct) YBa2Cu307 (YBCO)的超导性。包覆层使1-UCT YBCO具有超导性。结果表明，包-错-包电荷储层的形成对1-UCT YBCO的孔捐赠具有重要意义。在覆有Sr-O、Ca-O、Pb-0和Cd-O的1-UCT YBCO中也观察到超导性或电阻率的显著降低，这意味着电荷储层的形成。

Microstructures and Superconductivity of Ultrathin YBa₂Cu₃O₇ Films

Superconductivity of 1 unit cell thick (1-UCT) YBa2Cu307 (YBCO) with various oxide cap layers is studied. Capping with BaO layer makes 1-UCT YBCO superconducting. It is revealed that that a formation of BaO-CuO-BaO charge reservoir is of significance for the hole donation in the 1-UCT YBCO. Superconductivity or significant reduction of resistivity implying the formation of the charge reservoir was also observed in 1-UCT YBCO covered with Sr-O, Ca-O, Pb-0, and Cd-O.
