Mo3d, S2s (a) and S2p (b) XPS spectra of MoS 2 @MPC and …
We demonstrate a terahertz intensity modulator using a graphene supercapacitor which consists of two large-area graphene electrodes and an electrolyte medium. The mutual electrolyte gating between...

XPS 光谱解读. S2p 峰具有紧邻的自旋轨道分裂峰 (Δ=1.16 eV，强度比=0.511) 可以观察到硫单质和硫化合物的自旋轨道分裂。 用户通常观察到分裂谱或由于双峰未分离引起的峰形不对称，具体取决于化学状态和/或仪器分辨率。 如同 S2p，S2s 峰显示大范围的化学位移。
XPS分峰拟合，真的是哪里想要点哪里吗？ - 知乎专栏
当使用xps测试绝缘体或者半导体时，由于光电子的连续发射而得不到电子补充，从而使得样品表面出现电子亏损，这种现象称为“荷电效应”；荷电效应会使样品表面出现一稳定的电势v，对电子逃离具有束缚作用，引起能量的位移，导致实际测量的结合能偏离 ...

The high-resolution XPS spectra showed that the binding energies of Mo 3d 3/2 and Mo 3d 5/2 were located at 232.8 and 229.6 eV, respectively, which could be attributed to Mo 4+ in MoS 2 (Fig. 4a).

S2s peak, like S2p, shows a large range of chemical shifts. S2s peak has strong overlap with Se3s peak and Mo3d (particularly in sulfate/sulfonate chemical states, see Molybdenum section).

为什么我的XPS峰都这么尖锐，而文献中的峰都比较平缓，这说明了什么呀。 前两个图是我做的钼和硫，第三个图是文献中的. 高效液相色谱仪的... F-7000日立... 紫外可见光全波长... 老铁帮忙看看为啥... Pt 4f XP... 请问一下这个主峰... 太感谢亲了，亲应该是XPS砖家吧，我第一次做XPS，一上午了一个图也没分出来，再问一下亲，那个半峰宽都要一样大是分峰的必要条件吗？ 一定要FWHM全都一样大吗？ 这样的话分出来的峰好难看呀. 太感谢亲了，亲应该是XPS砖家吧，我 …
An XPS study of the surface modification of natural MoS
1998年9月1日 · Here, the chemical modification of single crystal natural 2H-MoS 2 using a radio-frequency (RF) oxygen plasma was characterised by XPS. The depth variation of the composition within the surface of the plasma-treated samples was also investigated.
