研究了80 K超导体Bi_2Sr_2CaCu_2O_（8 +y）中载流子浓度变化驱动的金属-绝缘体转变。载体浓度由钇取代钙来控制。从结构，运输和磁性研究的实验结果进行了讨论，与其他高温超导系统，La 2-xSrxCuO 4和YBa 2Cu 3 O 7-y的比较。
Metal-insulator transition driven by the change of the carrier concentration was investigated in the 80 K superconductor Bi2Sr2CaCu2O8+y. The carrier concentration was controlled by the substitution of yttrium for calcium. Experimental results from structural, transport, and magnetic studies are discussed in comparison with other high-temperature superconductor systems, La2-xSrxCuO4 and YBa2Cu3O7-y.
