摘要
利用化学喷雾沉积法(CSD法)在未定向的ZrO_2单晶衬底上获得了零电阻温度高于85 K和转变宽度为2 K、厚度小于5 μm的YBa_2Cu_3O_(7-δ)超导薄膜.以XRD、XPS和SEM等手段研究了不同制备条件下薄膜的晶体结构、电子结构和显微形貌,讨论了材料膜形成机制及其与超导电性的关系。
High Tc superconduction YBa2Cu3O76 thin film with zero resistivity temperature higher than 85 K and transition width of 2 K and thickness of 5 μm,on a substrate of crystal cubic ZrO2, was obtained by using Chemical Spray Deposition (CSD) process. XRD, XPS and SEM etc. were employed to investigate the crystallographic structure, electron structure and micro-morphology of films made under different conditions. The formation mechanism of YBa2Cu3O7δ, thin film and relation with superconductivity are discussed.
