XPS spectra of a B1s, b N1s, c C1s and d O1s for h-BN
Oxygen and carbon peaks shown in survey plot most likely resulted from the exposure of f-BNNSs to air or during the XPS measurement groundwork. The deconvoluted binding energies of B 1s at 189.6...
氮化硼(BN)常见的表征方法 - 知乎 - 知乎专栏
7、 x射线光电子能谱 (xps): 如图7b所示,ffsa的xps光谱揭示了n1s和o1s光谱的存在,可分别归因于研磨过程中涉及氧气和氮气的等离子体处理。与ffsa相比,ffsa9bn1和ffsa8bn2复合材料表面上的fe、si和al的特征峰几乎消失,表明复合材料的表面被h-bn致密覆盖。
请问XPS中的B 1s谱,C 1s谱,N 1s谱是什么谱图?1s代表什么意思?
这和普通的XPS图有什么区别? 还有,为什么B 1s的谱峰长得就和基线一样,小峰特别多,感觉信噪比很低;而C 1s谱和N 1s谱就很平滑,很好看呢? 谢谢. X-MOL学术平台旗下问答系统,汇集专家智慧,共同解决问题。 化学及相关领域的专业问题,包括实验原理、实验操作、反应路线、实验设计等,还有求职招聘及职场生涯的答疑解惑.
Direct growth of large-area graphene and boron nitride ... - Nature
2015年3月4日 · Here we report the direct growth of large-area graphene/h-BN vertical heterostructures by a co-segregation method. By one-step annealing sandwiched growth substrates (Ni (C)/ (B, N)-source/Ni) in...
X-ray photoelectron spectroscopy study of cubic boron nitride …
2012年2月1日 · The defects, impurities and their bonding states of unintentionally doped cubic boron nitride (cBN) single crystals were investigated by X-ray photoelectron spectroscopy (XPS). The results indicate that nitrogen vacancy (V N ) is the main native defect of the cBN crystals since the atomic ratio of B:N is always larger than 1 before Ar ion ...
