摘要： 用STM对含氧桥的金属-有机配合物[Cu2(μ-O)(dptap)4(NO3)2]分子在Au(111)表面的吸附行为进行了研究. STM结果表明, 该分子同时存在非解离吸附和解离吸附, 大部分分子在Au(111)面形成有规则的排列, 少量分子发生解离吸附, 并形成(√3×√3)R30°Cu原子吸附结构. 探讨了两种吸附现象共存的起因.

Abstract: The adsorption of metal-organic complex molecule ([Cu2(μ-O)(dptap)4(NO3)2], where dptap represents 2-(2-pyridylimino)-2H-1,2,4-thia-diazolo[2,3-a] pyridine) on Au(111) surface is studied by STM. STM results show coexistence of undissociative and dissociative adsorption of the molecule. The former shows regular arrangements of the molecule, while the latter gives a (√3×√3)R30°Cu adlayer structure. The possible origin of the coexistence of undissociative and dissociative adsorption is discussed.
