【摘要】 通过X光衍射、扫描电镜及红外光谱等手段,研究观察了YBa₂Cu₃O_7-x。超导体体材料及不同衬底薄膜在H⁺注入前后的电学性质和微观结构的变化情况。结果表明:注入H⁺后,微观结构和电学性能的变化与超导材料的内在质量有直接关系,微观结构的变化是导致YBa₂Cu₃O_7-x。超导材料电学性质变化的主要原因,H⁺注入后在YBa₂Cu₃O_7-x。中产生的Cu-H是次要或不重要的原因,并对H⁺在Y-Ba-Cu-O超导体中所起的作用作了一些评价。更多还原

【Abstract】 The variations of microstructure and electrically properties of YBa-Cu-O with and without H+ implantation have been studied by scanning electron microscope, X-ray diffraction and IR spectrum techniques. The results have shown that these variations are directly relative to the intrinsic quality of YBa2Cu3O7. Microstructural change is responsible for the variations of electrically properties of YBa2Cu3O7 superconductor. The Cu-H bond formed by H+ implanted into YBa2Cu3O7 is not a key factor for these variations.更多还原
