摘要：

测定了一系列氧化物的电子结合能，显示了铋系超导体与二元氧化物衬底材料的化学反应性可以用固态酸碱反应理论来描述，其反应性大小除了可以用衬底氧化物的酸碱参数估计以外，还可以用衬底氧化物氧离子的内层电子结合能估计．

关键词: Bi-Sr-Ca-Cu-O超导体, 固态酸碱反应, X射线光电子能谱

Abstract:

The O_(1s) binding energies of MgO, ZrO_2, TiO_2, Al_2O_3 and SiO_2 were determined by XPS. It is shown that the BSCCO-oxides interactions are predominately acid-base in nature, and the reactivity can be evaluated either by the acid-base parameter or by the core-level binding energy of oxygen of the oxide substrate materials.

Key words: Bi-Sr-Ca-Cu-O superconductor, Solid acid-base reaction, XPS
