本文采用分子束外延方法制备出MnSi薄膜和MnSi1.7纳米线, 利用扫描隧道显微镜进行观察, 采用X射线光电子能谱仪系统地分析了MnSi薄膜和MnSi1.7纳米线的Mn 2p和Si 2p. 结果表明厚度为 ～0.9 nm的MnSi薄膜表面为√3 × √3重构, MnSi1.7纳米线长500—1500 nm, 宽16—18 nm, 高 ～ 3 nm. MnSi薄膜的Mn 2p1/2和Mn2p3/2峰位与MnSi1.7纳米线相同, 均分别为649.7 eV和638.7 eV. 结合能在640—645 eV和 ～653.8 eV处的锰氧化合物的Mn 2p3/2和Mn 2p1/2 峰证明在短暂暴露于空气中后MnSi薄膜和MnSi1.7纳米线表面有氧化层形成. 两种锰硅化合物Si 2p谱中向低结合能方向的化学位移表明随着锰硅化合物的形成, Si的化学环境发生了变化.
