摘要
The experimental strategy of using pressure to amplify the influence of Ca-doping on the structure of Bi-2201 phase was proposed.Ca-doped Bi2201 crystals have smaller lattice volume, shorter c-axis, and are less compressible than the pure phase.The influence caused by the apical oxygen of the CuO6 octahedron on distortion of CuO2 plane is an important reason for increasing the Tc of the Ca-doped samples.
