Check for Co LMM Auger peak (713eV) or Ba4d peak (85eV) for confirmation. Cobalt oxides are readily reduced by Ar + sputtering. Use lowest possible ion beam energy when attempting to clean oxide sample surface or during depth profiling.

Co2p 区与自身一些较弱的 Co LMM 俄歇峰重叠，必须注意不要将该峰误判为 XPS 峰。 金属的 Co2p 峰形不对称。 高分辨金属Co的2p谱图显示了复杂的结构。 可以使用 Co2p 谱的卫星峰区分 Co 的各种氧化态。 Co (II) 具有可观察到的卫星峰 (~786eV)。 而 Co 3 O 4 实际上是 Co (II) 和 Co (III) 的混合氧化态，由于存在 2+ 和 3+ 态，我们预期会看到一些卫星峰。 碳可能会被注入金属Co中形成碳化物，例如，在氩离子深度剖析期间。 钴通常与镍联系在一起，因为这两种元素 …

Usually the Auger line Co LMM is quite broad, i.e. it is much broader than Co 2p peaks. Of course, the FWHM depends on the mode of your analyzer (mostly on the pass energy), but Co LMM is...

A simple one-step procedure for the preparation of cobalt oxide-carbon nitride composites by carrying out the thermal condensation reaction of carbon nitride precursors in cobalt (ii)...

Oct 13, 2023 · The Co LMM auger peak at 716.6 eV overlapped with the satellite peaks for Fe 2+ and Fe 3+. The Co 2p spectra were deconvoluted into a Co 2+ peak at 779.5 and a Co 3+ peak at 780.8 (Fig. 5c) 32.

Jan 22, 2009 · In this paper we study the formation of cobalt silicide on silicon and LP-CVD silicon oxide. The study was carried out on blanket and patterned wafers by the aid of Auger spectroscopy, electrochemical measurements and scanning electron microscopy (SEM).

同样，LMM俄歇电子是L层电子被激发，M层电子填充到L层，释放的能量又使另一个M层电子激发所形成的俄歇电子， 应该是俄歇线，属于伴峰。 请问，xps当中，KLL peak，与LMM peak分别代表什么峰？

然而，在利用Al Kα X射线源表征该类材料时，由于Co 2p特征峰和Co LMM俄歇峰部分重叠，导致在对Co进行定量分析时存在误差。 与之相反，在Cr Kα X射线源激发的全谱中，俄歇峰的位置发生改变（如图4所示），成功避免了Co 2p和Co LMM谱峰的重叠，从而实现更准确的 ...

Aug 1, 2009 · As the thickness of Co films increases above 5 monolayers (ML), pure cobalt islands form on the surface and the amount of oxygen on the surface layers increases with increasing the oxygen exposure time.

Jan 15, 2008 · The Co-LMM and O-KLL Auger electron diffraction patterns were obtained subtracting the background electron intensity from the intensity at the position of the Auger electron peak. On the basis of the Auger electron spectra a kinetic energy 20 eV higher than the maximum of the Auger emission line was chosen to record the background intensity.
