摘要: 利用化学喷雾沉积法(CSD法)在未定向的ZrO2单晶衬底上获得了零电阻温度高于85K和转变宽度为2K、厚度小于5μm的YBa2Cu3O7-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。

Abstract: High Tc superconduction YBa2Cu3O7-δ thin film with zero resistivity temperature higher than85 Kand transition width of 2 Kand thickness of 5 μm,on a substrate of crystal cubic ZrO2, was obtained by using Chemical Spray Deposition (CSD) process.XRD, XPSand SEMetc.were employed to investigate the crystallographic structure, electron structure and micro-morphology of films made under different conditions.The formation mechanism of YBa2Cu3O7-δ, thin film and relation with superconductivity are discussed.

Key words: Chemical spray deposition, Thin film, High Tc superconductor
