Introduce uniformly distributed ZnO nano-defects into BSCCO superconductors by nano-composite method

Uniformly distributed ZnO nano-defects were introduced into the BSCCO superconductors, using nano-composite method. The performance of superconductors and distribution of ZnO in superconductors according to different doping methods were researched. The results of standard four-probes method indicated that all those samples fabricated by different doping methods had obvious performance belonging to HTS. From the HRSEM images, we could see nano-ZnO (about 100 nm) defects linearly distributed on the surface of samples fabricated by nano-composite doping method.
